89, P-value 0.01) and traffic flow time (OR 9.06, P-value 0.01). On the other hand, the multivariate regression analysis only showed traffic flow time as the significant predictor (OR 6.27, P-value 0.02) at identified RTI prone-areas.

The measures devised to mitigate RTI in an emerging city like Kampala should study thoroughly the patterns of traffic and population flow to help to optimize the use of available resources for effective road safety planning, injury prevention and sustainable transport systems.

The C-terminal region (CTR) of Reelin is required for the correct formation of the superficial structure of the neocortex; however, the mechanisms by which this position-specific effect occurs remain largely unknown. In this study, we demonstrate that Reelin with an intact CTR binds to neuropilin-1 (Nrp1), a transmembrane protein. Both male and female mice were used. Nrp1 is localized with very-low-density lipoprotein receptor (VLDLR), a canonical Reelin receptor, in the superficial layers of the developing neocortex. It forms a complex with VLDLR, and this interaction is modulated by the alternative splicing of VLDLR. Reelin with an intact CTR binds more strongly to the VLDLR/Nrp1 complex than to VLDLR alone. Knockdown of Nrp1 in neurons leads to the accumulation of Dab1 protein. Since the degradation of Dab1 is induced by Reelin signaling, it is suggested that Nrp1 augments Reelin signaling. The interaction between Reelin and Nrp1 is required for normminal residues and Nrp1, a component of the canonical Reelin receptor complex.Two main subcortical pathways serving conscious visual perception are the midget-parvocellular (P), and the parasol-magnocellular (M) pathways. It is generally accepted that the P pathway serves red-green color vision, but the relative contribution of P and M pathways to spatial vision is a long-standing and unresolved issue. Here, we mapped the spatial sampling properties of P and M pathways across the human retina. Data were obtained from immunolabeled vertical sections of six postmortem male and female human donor retinas and imaged using high-resolution microscopy. Cone photoreceptors, OFF-midget bipolar cells (P pathway), OFF-diffuse bipolar (DB) types DB3a and DB3b (M pathway), and ganglion cells were counted along the temporal horizontal meridian, taking foveal spatial distortions (postreceptoral displacements) into account. We found that the density of OFF-midget bipolar and OFF-midget ganglion cells can support one-to-one connections to 1.05-mm (3.6°) eccentricity. One-to-one connections of cones to magnocellular (M pathway) through human retina. We find that P-type bipolar cells outnumber M-type bipolar cells at all eccentricities. We show that cone photoreceptors and P-type pathway bipolar cells are tightly connected throughout the retina, but that spatial resolution is lost at the level of the ganglion cells. Overall, the results support the view that the P pathway is specialized to serve both high acuity vision and red-green color vision.A group of experienced vets argue that the lack of control of endemically TB-infected communities of badgers has resulted in a bovine TB dilemma that is worse now than it was 50 years ago.Following on from the RCVS' series discussing key recommendations from its Legislation Working Party (LWP), RCVS registrar and director of legal services Eleanor Ferguson considers short-term proposals for reforming the RCVS disciplinary process.Gudrun Ravetz, chair of the BVA's Good Veterinary Workplaces working group, explains the rationale behind its new policy position - and why it is so important.Genetically engineered mosquitoes could help control the spread of diseases such as dengue, reports Kathryn Clark.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been caused the greatest pandemic of our century. Many of the deaths related to it are due to a systemic inflammatory response, which has been called 'cytokine storm'.

We developed a comprehensive review of the pathophysiology mechanisms of COVID-19 and of the rationale for drugs and therapeutics that have been tested in clinical trials.

A narrative review of the literature was conducted using PubMed, SciELO, Bireme, Google Scholar and ClinicalTrials.

SARS-CoV-2 has evolutive mechanisms that made it spread all around the globe, as a higher latency period and a lesser lethality than other coronaviruses. SARS-CoV-2 causes a delay in the innate immune response and it disarranges the immune system leading to an overwhelming inflammatory reaction (the 'cytokine storm'). In this scenario, high levels of interleukins (IL), notably IL-6 and IL-1, create a positive feedback of chemokines and immune responses, and powers pulmonary and systemic tissue damage, leading to capillary leakage and SARS, the main cause of death in patients with COVID-19. On 17 July 2020, there were 1450 entries on ClinicalTrials.gov of ongoing studies on COVID-19. The mechanisms of the main therapeutic approaches were comprehensively reviewed throughout the text. Therapies focus on blocking viral entry (remdesivir, umifenovir, among others) and blocking of immune system for cytokine storm control (IL-1 and IL-6 inhibitors, glucocorticoids, convalescent plasma, among others).

Understanding of action mechanisms of SARS-CoV-2 enables us to direct efforts on effective therapeutic targets. This comprehensive review helps to interpret the clinical results of the several trials ongoing.

COVID-19, being a very contagious disease, one has to be very careful and diligent in caring for our patients keeping safety in mind all the time. For day-to-day care, new norms have been adopted for inpatient care. For outpatient care, the face-to-face (F2F) clinics were cancelled and instead telephone consultations were started. read more However, it has its own limitations. Unfortunately, there were patients who would need F2F consultation but could not come to the clinic due to the infection risks. For those patients, video consultation was started, which was an innovation in practice. The National Health Service has an Attend Anywhere clinic, as part of transformation in service, which enabled remote consultation with a better outcome than telephone clinics. However, it has its own limitation as not everyone could use it.
