Southern blot analysis of Dra I-digested genomic DNA of L. paraplantarum strains using LpF2 as a probe showed that LpF2 is distinctive of strain FBA1 among 16 L. paraplantarum strains. Because PD0325901 in vitro both ERIC- and RAPD-PCR are fast and technically simple methods, they are useful for the rapid discrimination of L. paraplantarum strains

and for the development of new strain-specific DNA markers for identifying industrially important strains. Lactobacillus paraplantarum, a species phenotypically close to Lactobacillus plantarum, was characterized in 1996 (Curk et al., 1996). Few phylogenetic studies of the species have been reported (Torriani et al., 2001a, b), and methods for discrimination between strains have yet to be developed. On the other hand, some L. paraplantarum strains have received

attention owing to their potential uses in food production or preservation (Lee et al., 2007; Chun et al., 2008). We evaluated the effects of 200 heat-killed lactic acid bacteria (LAB) strains on the production of hyaluronate and type I collagen when applied to normal human dermal fibroblast cells in vitro and found five strains with high efficacy (S. Miyata , K. Yamamoto, S. Sakata, C. Suzuki, H. Kimoto-Nira, K. Mizumachi & Y. Kitagawa, unpublished data). These strains (including one called FBA1) improved the skin integrity of HR-1 hairless mice fed a reduced-protein diet. These effects are strain dependent; hence, it is important to develop reliable methods to identify and discriminate strains of L. paraplantarum. CX-4945 Enterobacterial repetitive intergenic consensus (ERIC) sequences are highly conserved DNA sequences that occur as multiple copies in the genomes of enteric bacteria and Vibrio species (Sharples & Lloyd, 1990; Mercier et al., 1996; Tcherneva et al., 1996; Wilson & Sharp, 2006). Methods using ERIC-PCR have been used to classify closely related strains of enterococci (Wei et al., 2004). The random amplified polymorphic DNA (RAPD) method has been used to classify various organisms

from bacteria to plants (Van Reenen & Dicks, 1996; Torriani et al., 2001a; Venkatachalam et al., 2004; Nomura et al., 2006; Walczak et al., 2007). RAPD entails PCR amplification with a single, short oligonucleotide primer that does not strongly match particular sites in target genomes, Oxymatrine under low-stringency conditions, for annealing. In most cases, both ERIC- and RAPD-PCR generate several DNA bands that enable species-level or sometimes strain-level differentiation of bacteria. The aim of this study was to develop a fast and simple method to discriminate strains of L. paraplantarum using PCR and to develop a DNA marker to identify specifically the particular strain. We focused on an L. paraplantarum FBA1 strain, which improved the skin integrity of HR-1 hairless mice fed a reduced-protein diet, and developed a pair of FBA1-specific PCR primers and an FBA1-specific DNA fragment based on ERIC-PCR.

We are of course always encouraging of any additional research that provides an evidence base for improved immunization practice. Colleen Lau, *† Deborah Mills, ‡ and Philip Weinstein * “
“Pulmonary histoplasmosis is a rare disease in France, where all cases are imported. Diagnosis is difficult in nonendemic areas, often based on travel history and observation of epidemic in a group. We report three cases of pulmonary histoplasmosis that occurred in a group of 12 French cavers traveling to Cuba. Pulmonary histoplasmosis is a

rare disease in France, as in Europe.1 Excluding cases identified in Guyana and Caribbean islands, only 18 cases of histoplasmosis due to Histoplasma capsulatum var. capsulatum have been reported in France in 2008 by the Centre

National de Référence Fulvestrant de la Mycologie et des Antifongiques check details (CNRMA), Institut Pasteur, Paris, France. All of them were imported from endemic areas. Infection results from inhalation of fungal spores, present in soil contamined by bat or bird droppings.2,3 Clinical manifestations and radiological features of acute pulmonary histoplasmosis are nonspecific2,4,5 and depend on the size of the inoculum.4,5 Moreover, in this clinical presentation, serological test and culture of sputum can be negative.2,4,5 For all these reasons, diagnosis of acute pulmonary histoplasmosis remains difficult in nonendemic areas, often based on travel history and risk factor, such as caving.6 A group of 12 French cavers traveled to Cuba from February 17 to March 4, 2008. During their trip, they visited four bat-infested caves in the Sierra de Los Organos, west Cuba: Red Ojo del Agua, Red Rio Blanco, Cueva Manuel Noda, and Cueva Del Hoyo Del Nodar. After their return to France, three of them developed fever, cough, asthenia,

Amobarbital dyspnea, and chest pain. The first patient, a previously healthy 40-year-old man, was admitted in the Grenoble University Hospital, France, because of fever, dyspnea, and chest pain 3 days after he came back. Physical examination was unremarkable. Chest radiography showed a miliary, and computed tomography (CT) scan confirmed the presence of bilateral multiple pulmonary nodules, micronodules, and ground glass opacities. Laboratory findings included slightly elevated liver enzymes and moderate inflammatory reaction (C-reactive protein, 40 mg/L–normal < 3 mg/L). Bronchoalveolar lavage (BAL) did not show any bacterial, mycobacterial, or fungal agents neither by direct examination nor by cultures. Serological test was positive, but not performed in the CNRMA (by immunodiffusion: H precipitin band, one precipitin arc). The patient was treated with itraconazole 400 mg/d for 3 months. After therapy, we noted a clinical and radiological improvement.

The essential genes of mycoplasmas have been compared often to those PD98059 cell line of B. subtilis because of their phylogenetic relationship (Glass et al., 2006; Dybvig et al., 2008; French et al., 2008). Three of the M. pulmonis genes

knocked out by the minitransposon have essential orthologs in B. subtilis (Table 1). Interestingly, orthologs of these three genes are nonessential in M. genitalium. The tkt gene coding for transketolase is essential in B. subtilis for growth in minimal medium when using glucose as the sole carbon source (Kobayashi et al., 2003), but is nonessential when alternative carbon sources and aromatic amino acids are available (Sasajima & Yoneda, 1974; Sasajima & Kumada, 1981). The finding that tkt

(MYPU_5110) is nonessential in mycoplasmas is not surprising because of the rich medium required for growth. The other two genes that are essential for the growth of B. subtilis but not the mycoplasmas coded for SMC (MYPU_7140 gene product) and the segregation and condensation protein ScpA (MYPU_1150 gene product). These proteins colocalize in B. subtilis and are required for growth at temperatures above 23 °C and for normal chromosome segregation (Mascarenhas et al., 2002). The M. pulmonis mutants used in this study were grown at 37 °C, the optimal growth temperature for this organism. Perhaps the processes of chromosome segregation and cell division differ in mycoplasmas from those of other bacteria because of the lack of a cell wall, rendering the SMC and ScpA proteins dispensable under normal growth conditions. PCR analysis of minitransposon mutants provided evidence for gene duplication. STI571 research buy For some mutants, the PCR amplifications performed to verify that a gene was disrupted yielded a product confirming that the transposon disrupted the gene but also yielded a second product indicative of an intact copy of the gene. The discrepancy could be resolved usually by subcloning the mutant. In most cases, when

individual subclones were analyzed by PCR, at least one subclone had Protein tyrosine phosphatase the gene disrupted with no intact copy present. Thus, the gene was mutable. In a few cases, the PCR analyses indicated that all subclones, five were analyzed, had both a disrupted and an intact copy of the gene (Table 2). The duplications were not necessary to maintain viability due to the inactivation of essential genes. The genes disrupted in transformants JS003 and JS170 are not essential because other transformants in the library had the same genes inactivated without an intact copy being present, and transformant JS620 has the transposon inserted into an intergenic region with apparent duplication. Little is known about the frequency and size of duplications in mycoplasmal genomes, but several examples of duplicated sequences have previously been described in M. pulmonis (Bhugra & Dybvig, 1993; Dybvig et al., 1998; Shen et al., 2000; Dybvig et al., 2007).

From comparative genome sequences that indicated the high similarity among B. mallei, B. thailandensis and B. pseudomallei (Nierman et al., 2004; Yu et al., 2006), it is not surprising that these tested lytic phages as well as lysogenic phi1026b of B. pseudomallei and phiE125 phage of B. thailandensis could lyse B. mallei (Woods et al., 2002; DeShazer, 2004). From the host challenge tests, ST79 and ST96 phages could rapidly lyse B. pseudomallei strain P37 in vitro

but the bacteria were able to regrow 6 h after addition of phages (Fig. 3). The observed regrowth might be due to a host population that was able to resist phage lysis or to the bacterial cell debris containing phage receptors that partially blocked phages from reinfection. Other reports also demonstrated the incomplete selleck kinase inhibitor lysis of the host culture after phage challenge including Salmonella phages and E. coli O157 phage (Los et al., 2003; Fischer et al., 2004; Carey-Smith et al., 2006). MAPK Inhibitor Library solubility dmso In a case of E. coli O157:H7 cultured with phages e11/2, pp01 and cocktail phages, results showed the presence of phage-insensitive mutants at a very low frequency (10−6 CFU) following the challenge (O’Flynn et al., 2004). Phage ST79 possesses a medium-sized head (146 × 17 nm) and large burst size (304 particles/infected cell) when compared with other lytic phages. The small T7-like

lytic phage IBB-PF7A (head 13 × 8 nm), specific to Pseudomonas fluorescens, exhibits much shorter eclipse and latent periods than ST79 (10 and 15 min) and a smaller burst size (153 particles per infected cell) (Sillankorva et al., 2008). In contrast, the giant phages FGCSSa1 and φSMA5 (highly selective for Salmonella spp. and S. maltophilia) have longer latent periods (50 and 80 min) but smaller burst sizes (139 and 95 particles per infected cell) (Change et al., 2005; Carey-Smith et al., 2006). Further studies of these phages’

receptors and their whole genome sequences, which are under investigation, should provide basic genetic information to support the possibility that these phages, either as individuals or as a part of cocktails, could be useful for biocontrol or as a therapeutic agent for B. pseudomallei.

“Hepcidin belongs to the antimicrobial peptide (AMP) family and is the key regulator of iron metabolism. It modulates iron homeostasis by binding to, and degrading the iron exporter molecule, ferroportin, thus inhibiting cellular iron efflux.

Our Bayesian estimates are not very different from the usual maximum likelihood estimates. This should reassure clinicians who worry that the “use of Bayesian procedures will set the stage for the

entry of non-fact-based information that, Selleck Olaparib unable to make it through the ‘evidence-based’ front door, will sneak in through the back door of ‘prior distributions’ ” [28]. The key is to use vague, but not uninformative, prior distributions – the statistical equivalent of keeping an open mind. Where there is sufficient information in the data, the prior has no influence (on continuous predictors such as age, viral load and CD4 cell count; Table 3). Where there is less information, the influence of the prior is often subtle, curbing the more extreme limits of the maximum likelihood estimate (as in the upper limit of the CI for female patients; Table 3), but is sometimes obvious (as in the upper limit of the CI for resistance to darunavir under variants 1 and 2; Table 4). One would not usually expect reliable maximum likelihood estimates given a model with six or seven predictors and only 18 to 29 events. As a rule, time to event analyses require 10 to 15 events per predictor [29]. With too few

events, maximum likelihood estimates are often biased away from the null value (a hazard ratio of 1) [30]. A well-chosen prior will Quizartinib manufacturer limit this sparse data bias, constraining posterior estimates to lie within a plausible range by assigning essentially zero prior probability to extreme values. The usual maximum likelihood estimates are just extreme Bayesian estimates using completely

uninformative priors where extreme hazard ratios (such as ratios of 20) are seen as just as likely as ratios that are clinically far more plausible in studies of this sort (such as ratios of 1 or 2) [26]. In other similar studies Erastin cell line of darunavir, there is evidence of sparse data bias in estimates of odds ratios [31,32]. It is hard to find a study of risk factors for virological failure in salvage therapy that does not involve stepwise variable selection, variable selection based on the results of univariate tests or the fitting of overly simplistic models; yet these strategies lead to models and estimates that are not reliable and do not replicate [29,33]. Invariably some covariates are omitted in an attempt to more reliably estimate others. Omitting covariates is equivalent to a very strong and often unreasonable prior opinion that the omitted covariates have no effect at all on outcome. A better strategy is to retain covariates and use prior information to constrain estimates to lie within a plausible range. This study suggests that, when used for salvage therapy, darunavir can achieve a similar efficacy and tolerability in clinical practice to that seen in clinical trials.

In addition, strain

BFLP-4T could be differentiated from related species on the basis of some biochemical properties such as negative utilization of d-fructose and d-mannose. Other physiological characteristics of strain BFLP-4T are shown in Table 1 and also in the species description. The 16S rRNA gene sequence of strain BFLP-4T was a continuous stretch of 1417 bp. Sequence similarity calculations after a neighbour-joining analysis indicated that the closest relatives of strain BFLP-4T were V. ichthyoenteri (97.1%), V. mediterranei (96.7%), V. scophthalmi (96.7%) and V. sinaloensis (96.6%). Similar results were obtained for strain BFLP-4T when the maximum-parsimony algorithm was used (Fig. S1). The recA gene has also been proposed as a useful Temsirolimus marker in inferring bacterial phylogeny (Lloyd & Sharp, 1993; Eisen, 1995), and has been used successfully to differentiate species of the genus Vibrio (Thompson et al., 2005). A pairwise analysis of the recA sequence of strain BFLP-4T also revealed low levels of similarity between this strain and several species from the genus Vibrio (Fig. 3). For example, BFLP-4T exhibited 90.5% similarity to V. harveyi BAY 57-1293 LMG 4044T, 90.2% to V. rotiferianus LMG 21460T and 89.5% to V. campbellii LMG 11216T. The major fatty acids in strain BFLP-4T were summed feature 3 (comprising C16:1ω7c and/or C15:0 iso 2-OH), C16:0, C18:1ω7c and C14:0, which comprise approximately

80.7% of the cellular fatty acids extracted. Fatty acids C16:1ω7c and/or C15:0 iso 2-OH, C16:0, C18:1ω7c, C14:0, C12:0 and C16:0 iso are typically the major fatty acids found in Vibrio species (Thompson & Swings, 2006). However, strain BFLP-4T and most closely related type strains, V. ichthyoenteri, V. mediterranei, Vibrio shilonni and V. sinaloensis, could be clearly distinguished from each other

based on the relative fatty acid concentration. The DNA G+C content was calculated to be 49.3 mol%. This value is within the range for the genus Vibrio (Farmer, 1992). Therefore, the phenotypic and genotypic properties of strain BFLP-4T support its description next as a novel species within the genus Vibrio, for which the name Vibrio hippocampi sp. nov. is proposed. Vibrio hippocampi (hip.po.cam’pi. L. gen. n. hippocampi, of the seahorse, isolated from H. guttulatus). Cells are Gram-negative, motile, facultatively anaerobic and slightly curved and rod-shaped (1.0 × 2.0–2.5 μm). Colonies on TSA supplemented with 1.5% w/v NaCl are cream coloured, circular and 1.5–2.0 mm in diameter. Optimum growth temperature is 20 °C. No growth occurs below 10 °C or above 35 °C. Growth occurs at pH 5.5–9.0, but not below pH 5.0 or above pH 9.0. Growth occurs at NaCl concentrations between 0% and 7% w/v, but not in the presence of 8% w/v NaCl. Positive for catalase, oxidase; nitrate reduction to nitrite; N-acetyl-d-glucosamine; assimilation of d-glucose and d-maltose.

, 1997; Croci et al., 2007). However, due to the presence of both false-positive and false-negative results in all the biochemical identification methods proposed, some authors (O’Hara et al., 2003; Thompson et al., 2004; Croci et al., 2007) suggested caution in the interpretation of such identifications and advise the use of additional confirmatory testing, such as PCR, Afatinib which enables the detection of the specific nucleotide sequence of V. parahaemolyticus. To specifically detect V. parahaemolyticus by PCR, several researchers used the species-specific targets toxR

gene (Kim et al., 1999; Deepanjali et al., 2005; Croci et al., 2007) and the thermolabile hemolysin gene (tlh) (Bej et al., 1999). Recently Croci et al. (2007), utilizing Vibrio strains (reference, environmental and clinical strains) already identified by API 20E, API 20NE (API; bioMérieux, Marcy l’Etoile, France) and Alsina’s scheme (Alsina & Blanch 1994a, b), conducted a multicenter evaluation of biochemical and molecular methods for V. parahaemolyticus identification and found that Alsina’s scheme for biochemical characterization and toxR gene detection Metformin clinical trial for molecular analyses produced the best results for inclusivity, exclusivity and concordance. In addition, to determine the real risk posed to human health by the presence of V. parahaemolyticus,

strain identifications must very be followed by the detection of the pathogenicity marker genes: tdh (thermostable-direct hemolysin) and trh (thermostable-related hemolysin) (Bej et al., 1999). In the present study, aimed at investigating the presence of V. parahaemolyticus in two coastal sites in the Gulf of Trieste (North Adriatic Sea), to select environmental strains, we used the same three biochemical identification methods (Alsina’s scheme, API 20E and API 20NE) using media and bacterial suspensions with a slight modification of the salinity from 0.9% to 3% NaCl. Subsequent molecular analyses were performed to confirm phenotypic characterizations. The PCR results for the 16S rRNA gene, toxR and tlh genes

were compared with biochemical characterizations of V. parahaemolyticus environmental strains to evaluate the effectiveness of the biochemical methods applied. Finally, to investigate the spreading of pathogenic traits, the isolates were subjected to PCR assays to detect tdh and trh genes. The environmental strains had been isolated from a total of 24 seawater samples collected during a monitoring program carried out monthly throughout 2003, which aimed to investigate the presence of vibrios in two sites in the Gulf of Trieste (NE Adriatic Sea): C1 (45°42′03″N, 813°42′36″E) is about 200 m offshore and D2 (45°45′49″N, 13°35′36″E) is 1250 m offshore and is located near the Isonzo River delta. Surface (−0.

Factors associated with the presence of OA were identified. A total of 7126 permanent residents were surveyed and 1734 (24.3%) had OA. Knee OA was the most prevalent form of OA (13.8%), followed by lumbar (7.4%), cervical (3.4%), hand (3.3%), shoulder (3.0%), elbow (2.9%),

ankle (0.7%), hip (0.6%), wrist (0.5%), thoracic (0.5%) and foot OA (0.5%). All of knee, ankle, shoulder and hand OA exhibited a gender bias. Advanced age, a sweet tooth, poor home ventilation, poor home heating, separation, divorce, or death of a partner, low-grade occupation, low educational level, high body mass index and the presence of concomitant cardiovascular disease, were associated with the presence of OA. Symptomatic OA is very selleck chemicals llc prevalent in rural regions of Shanxi Province. Many factors increase the prevalence of the condition. Primary and secondary prevention programs seeking to improve living conditions, to reduce obesity, and to effectively treat concomitant cardiovascular disease, are required. “
“The present paper aims to review the recent advances in diagnosis and management of ankylosing spondylitis (AS). Medline and abstracts submitted to the recent European League Against Rheumatism (EULAR) congress were searched to obtain quality-controlled information on the management of AS. The use of magnetic resonance imaging (MRI) allows the diagnosis of AS to be made in the pre-radiographic

stage. The Assessment in Spondylarthritis International Society recommendations for the management of AS have been modified so that patients with non-radiographic spondyloarthritis (SpA) can now be considered for biological therapy. The ‘older’ anti-tumour necrosis factor (TNF) continued LY2157299 to be effective in longer-term studies. Studies with longer duration of follow-up have shown that some patients with pre-radiographic SpA entered into prolonged drug-free remission. It is likely that in the foreseeable future, more AS patients

will be treated with biological therapies at an earlier stage Mannose-binding protein-associated serine protease of the disease. New biologic therapies, golimumab and secukinumab, are looking promising in improving the signs and symptoms of AS, at least in the short-term. Longer-term studies of AS patients treated with infliximab, etanercept and adalimumab continued to show a good clinical response. There is a need for more long-term studies to examine the longitudinal efficacy of golimumab and secukinumab in AS. “
“To describe the spectrum of diseases seen in an outpatient setting in the Singapore General Hospital, the largest tertiary referral centre in Singapore. In this cross-sectional study, medical records of patients scheduled for an appointment at the rheumatology specialist outpatient clinics over a 4-month period (10 August 2010–31 December 2010) were reviewed. Primary diagnoses documented by the attending physician at the latest visit were recorded. Among 4180 patients (29.5% male; mean [SD] age: 53.5 [15.1] years; 77.0% Chinese, 8.

Data were analysed using spss version 18 (SPSS Inc., Chicago, IL, USA). Proportions were compared using the χ2 test and ages were compared by means of a one-way analysis of variance (ANOVA). P-values of <0.05 were considered

statistically significant. The ethical committee of Hospital São João approved the study design in 2007. No specific consent was obtained from the patients as the data were used anonymously. As shown in Table 1, in the sample as a whole there were similar proportions of male and female patients. Patients followed in the southern area of the country represented 59% of the sample population. Dual infections (HIV-1 and HIV-2) accounted for a minority (3.6%) of cases. Around half of the patients were Portuguese citizens (213; 48.2%).

Guinea Bissau, learn more Cape Verde and Angola were the countries of origin of 33.5, 7.9 and 2.5% of the patients, respectively. The mode of transmission was mainly reported as heterosexual (260; 58.8%). Blood transfusions were the route for HIV-2 transmission in 15.4% of cases, but the proportion of cases attributed to blood transfusions has been declining over time. Injecting drug use was the mode of acquisition selleck screening library in 2.3% of patients and men who have sex with men accounted for 1.1%. Vertical transmission was rare (0.9%). The mode of transmission was not specified for 21.5% of the participants. The majority of the patients were asymptomatic at diagnosis (283; 64.0%). Lymphocyte CD4 cell count at diagnosis was available for 62% of the patients. Of these, 62 (22.6%) had a CD4 count <200 cells/μL. At the last follow-up evaluation, most patients remained treatment-naïve (200; 45.2%). However, 156 (35.3%) were on antiretroviral therapy, 14.5% of whom had experienced at least two different treatment regimens. During follow-up, at least 23.7% developed

AIDS. By the end of December 2007, 128 (29%) of the patients were alive; 82 (18.6%) had died. For 232 (52.5%), the outcome was unknown. HIV-2 infection diagnoses were distributed over time as follows: 1985 to 1989, 57 patients; 1990 to 1994, 83 patients; 1995 to 1999, 95 patients; 2000 to 2004, 127 patients and 2005 to 2007, 73 patients (Table 2). For seven patients, the year of diagnosis was not specified. Janus kinase (JAK) Before 1989, the majority of patients were male (39; 68.4%), had Portuguese nationality (45; 78.9%) and were living in the north of the country (44; 77.2%). The mean age at diagnosis was 31.0 (±14.7) and 37.8 (±8.9) years for male and female patients, respectively. Most patients were infected through heterosexual intercourse (31; 54.4%), but the proportion of HIV-2 infections attributed to blood transfusions was high (22; 38.6%). Forty-one individuals (71.9%) were asymptomatic at the time of diagnosis. From 1990 to 1994, the numbers of cases of newly diagnosed HIV-2 infection were nearly equal in men and women (41 men and 42 women). Heterosexual transmission remained the main transmission route (61.4%), followed by blood transfusion (31.3%).

The causality of this relation is shown both by the elongation of hand reaction and movement time and by spatial dispersion of hand trajectories after muscimol injections limited to the SPL area, where these relationships between neural activity and hand kinematics have been found (Battaglia-Mayer et al., 2006b). Consistent with this picture, the failure of optic ataxia patients

to make fast, in-flight corrections of hand movement trajectory may MG132 be due to the loss of those populations of parietal cells whose activity carries predictive signals concerning corrections of hand movement direction. These results are consistent also with those obtained approximately 25 years ago by a similar study of motor cortex (Georgopoulos et al., 1983). Motor cortex is linked

to SPL both directly (Strick & Kim, 1978; Johnson et al., 1996) and indirectly, through dorsocaudal premotor cortex (Johnson et al., 1996; Matelli et al., 1998). Transient inactivation of premotor cortex with transcranial magnetic stimulation results in a reduction in visually-dependent on-line corrections of reaching during sensorimotor adaptation (Lee & van Donkelaar, 2006). Therefore, it is reasonable to assume that the visuomotor information used by motor cortical cells to update hand movement trajectory in response to a change in target location originates in large Osimertinib in vitro part from the SPL. Directional hypokinesia is found after both frontal and inferior parietal lesions, and is characterized by an impaired representation of action space, evident as a difficulty in planning and execution of hand movements toward the contralesional part of egocentric space. More specifically, directional hypokinesia involves a prolongation of reaction and movement time, as well as an increased inaccuracy of reaching to visual targets in the contralesional part of space, regardless filipin of the limb used. Directional hypokinesia often coexists with directional bradykinesia and hypometria, so that arm movements have reduced velocity and amplitude as well. These features, together with the difficulty of initiating the movement, distinguish

directional hypokinesia from optic ataxia. Directional hypokinesia is generally considered the hallmark of the output-related components of neglect (Watson et al., 1978; Heilman et al., 2000; for reviews see Vallar et al., 2003; Fink & Marshall, 2005). In an attempt to better characterize directional hypokinesia, neglect patients with inferior frontal and parietal lesions in the right hemisphere (Mattingley et al., 1992, 1998) have been contrasted when making reaches performed to left visual targets from right and left starting positions relative to the movement end-point. Under this condition, both frontal and parietal patients displayed longer reaction times to initiate the reach toward the contralesional target.
