Transhumance, a main ancestral animal production strategy of the West African Countries (WAC), can favour the spread of vectors and vector-borne diseases within and/or across countries. Transhumance has been implicated in such spread as well as that of related tick-borne diseases (TBD).

Using a questionnaire survey and statistical modelling, this study explores the perception of herders about ticks and TBD in cattle, their practices in tick control and the social groups involved in cattle farming in eastern Burkina Faso (46 random herds) and in the northern Benin (44 random herds). Results show that most of the herders (79%) are from the Fulani social group. The principal and secondary activities of herders are respectively cattle farming and agriculture. The mean age of pastoralists is between 40 and 50years depending on the province of origin and 60% of the surveyed herds practice internal or transboundary transhumance. Herders have a clear knowledge of different genus of ticks except the genus Rhipicepch results would help to elaborate suitable strategies of control and prevention of ticks and TBD in Burkina Faso and Benin.Since December 2019, SARS-CoV-2 has spread extensively throughout the world, with more than 117 million reported cases and 2.6 million deaths (Johns Hopkins coronavirus resource center, https//coronavirus.jhu.edu/map.html). Detecting the virus is the first step in diagnosing the infection, followed by quarantine to prevent transmission. Nasopharyngeal/oropharyngeal swabs (NP/OP) and saliva are two specimen types that are most often analyzed to detect SARS-CoV-2 by molecular tests that detect viral RNA or by antigen/antibody tests that detect viral proteins and/or the host immune response against the virus. Compared to antigen/antibody tests, molecular tests are highly sensitive and specific for detecting the virus. A significant drawback is that specimen collection requirements are specific to each test and cannot be interchanged with another test. Some tests are qualified to be used on NP swabs or saliva, but not both specimen types. Even with NP swabs, a test may be qualified to detect the virus only with sected in different media, and from saliva Alternate Protocol 1 Low-throughput automated extraction on the Qiagen EZ1 Advanced XL machine (1-14 samples) Alternate Protocol 2 High-throughput automated extraction on the Kingfisher Flex machine (1-96 samples) Basic Protocol 2 Multiplex RT-qPCR protocol to detect SARS-CoV-2 Alternate Protocol 3 Multiplex one-step RT-qPCR protocol to detect SARS-CoV-2 with S and E gene probes labeled with the same fluorochrome.

Dermatitis herpetiformis (DH) is a chronic, pruritic, gluten-induced skin disorder characterized by subepidermal granular IgA deposition and a variable degree of enteropathy identical to that seen in coeliac disease. So far, there has been no European consensus about the management of DH.

The guidelines were created by small subgroups of a guideline committee consisting of 26 specialists from various medical fields and one patients' representative. The members of the committee then discussed the guidelines and voted for the final version at two consensus meetings. The guidelines were developed under the support of the European Academy of Dermatology and Venereology (EADV) and in collaboration with the European Dermatology Forum (EDF).

The guidelines summarize evidence-based and expert-based recommendations (S2 level) for the management of DH (see Appendix).

These guidelines will improve the quality of management of DH and support dermatologists in their diagnostic and therapeutic decisions.

This study provides insights into the physiological function of Asn in T cell activation and effector functions, showing the encouraging possibility of key metabolites for empowering cancer immunotherapy.The optimal use of legume genetic resources represents a key prerequisite for coping with current agriculture-related societal challenges, including conservation of agrobiodiversity, agricultural sustainability, food security, and human health. Among legumes, the common bean (Phaseolus vulgaris) is the most economically important for human consumption, and its evolutionary trajectories as a species have been crucial to determining the structure and level of its present and available genetic diversity. Genomic advances are considerably enhancing the characterization and assessment of important genetic variants. For this purpose, the development and availability of, and access to, well-described and efficiently managed genetic resource collections that comprise pure lines derived by single-seed-descent cycles will be paramount for the use of the reservoir of common bean variability and for the advanced breeding of legume crops. This is one of the main aims of the new and challenging European project INCREASE, which is the implementation of Intelligent Collections with appropriate standardized protocols that must be characterized, maintained, and made available, along with the related data, to users such as breeders and researchers. © 2021 The Authors.

Fine-needle aspiration cytology (FNAC) has become one of the most useful modalities for diagnosis and staging of lymphoma. However, diagnostic accuracy of this technique has been reported with varying results across several studies around the world. Hence, this meta-analysis was done to assess the accuracy of FNAC for lymphoma diagnosis.

We conducted a systematic search for all studies reporting the diagnostic accuracy of FNAC for lymphoma in the databases of PubMed Central, MEDLINE, EMBASE, MEDLINE, SCOPUS and Cochrane library from inception till January 2021. Meta-analysis was performed using STATA software "midas" package.

Forty-seven studies with 7268 patients were included. The pooled sensitivity and specificity of FNAC for diagnosing lymphoma were 93% (95% CI, 90%-95%) and 97% (95% CI, 95%-98%), respectively. Likelihood ratio positive was 33.5 (95% CI, 18.5-60.7) and likelihood ratio negative was 0.07 (0.05-0.11) making the technique to occupy the left upper quadrant in LR scattergram indicating that FNAC can be used for confirmation and exclusion. There was significant heterogeneity with significant chi-square test and I

statistic >75%. There was significant publication bias as per Deek's test and funnel plot.

To summarize, our study found that FNAC has a vital role as a diagnostic tool for lymphoma with higher sensitivity and specificity. Further studies assessing the accuracy of FNAC on specific types of lymphoma is required.

We sought to (1) determine the prevalence of cardiac changes in patients with ESLD awaiting OLT (2) determine relationship between nutritional indices and cardiac changes.

Retrospective review of transthoracic ECHO, clinical and nutritional information of pediatric patients evaluated for OLT. ECHO was analyzed for LVH, defined as LVMI>95g/m

and/or RWT>0.42. These findings were correlated with age, ESLD etiology, growth and nutritional parameters as well as pre- and post-OLT.

Sixty-five patients were included, all had normal left ventricular systolic function. K-Ras(G12C) inhibitor 12 cost Nine patients (14%) had LVMI>95g/m

, five patients (8%) had RWT>0.42, none met both criteria. None had thickened interventricular septal wall. Fourteen patients (20%) had significant left ventricular dilation. Nutritional deprivation was modestly present-weight under third percentile in 22%, length under third percentile in 24%, and both weight and length under third percentile in 17%. There were 12 patients (17%) with MUAC below two standard deviations for age; of these one had an elevated LVMI and another had an RWT>0.42.

In this contemporary cross-sectional evaluation, a smaller proportion of patients with ESLD had LVH in contrast to prior studies. Despite a comparable disease burden, our cohort had better nutritional status. Though there was a trend between nutritional and LVH indices, this correlation may be better assessed prospectively in a larger cohort.

Therapeutics targeting different components and processes of the viral infection replication cycle are being investigated, particularly to repurpose already approved drugs. Spike protein is an important target for both vaccines and therapeutics. Insights into the mechanisms of spike-ACE2 binding and cell fusion could support the identification of compounds with inhibitory effects. Here, we demonstrate that the integrity of disulfide bonds within the receptor-binding domain (RBD) plays an important role in the membrane fusion process although their disruption does not prevent binding of spike protein to ACE2. Several reducing agents and thiol-reactive compounds are able to inhibit viral entry. N-acetyl cysteine amide, L-ascorbic acid, JTT-705, and auranofin prevented syncytia formation, viral entry into cells, and infection in a mouse model, supporting disulfides of the RBD as a therapeutically relevant target.The genetic and phenotypic characterization of crops allows us to elucidate their evolutionary and domestication history, the genetic basis of important traits, and the use of variation present in landraces and wild relatives to enhance resilience. In this context, we aim to provide an overview of the main genetic resources developed for lentil and their main outcomes, and to suggest protocols for continued work on this important crop. Lens culinaris is the third-most-important cool-season grain and its use is increasing as a quick-cooking, nutritious, plant-based source of protein. L. culinaris was domesticated in the Fertile Crescent, and six additional wild taxa (L. orientalis, L. tomentosus, L. odemensis, L. lamottei, L. ervoides, and L. nigricans) are recognized. Numerous genetic diversity studies have shown that wild relatives present high levels of genetic variation and provide a reservoir of alleles that can be used for breeding programs. Furthermore, the integration of genetics/genomics and breeding techniques has resulted in identification of quantitative trait loci and genes related to attributes of interest.
