Social insects vary widely in social organization, yet the genetical and ecological factors influencing this variation remain poorly known. In particular, whether spatially varying selection influences the maintenance of social polymorphisms in ants has been rarely investigated. To fill this gap, we examined whether fine-scale habitat heterogeneity contributes to the co-existence of alternative forms of social organization within populations. Single-queen colonies (monogyne social form) are generally associated with better colonization abilities, whereas multiple-queen colonies (polygyne social form) are predicted to be better competitors and monopolize saturated habitats. We hypothesize that each social form colonizes and thrives in distinct local habitats, as a result of their alternative dispersal and colony founding strategies. Here, we test this hypothesis in the Alpine silver ant, in which a supergene controls polymorphic social organization.
Monogyne and polygyne colonies predominate in distinct hat that spatially varying selection may be one of the mechanisms contributing to the maintenance of genetic polymorphisms in social organization.
Alternative social forms colonized and monopolized different local habitats, in accordance with differences in colonization and competition abilities. The monogyne social form displays a colonizer phenotype, by efficiently occupying empty habitats, while the polygyne social form exhibits a competitor phenotype, thriving in saturated habitats. The combination of the two phenotypes, coupled with fine-scale habitat heterogeneity, may allow the coexistence of alternative social forms within populations. Overall, these results suggest that spatially varying selection may be one of the mechanisms contributing to the maintenance of genetic polymorphisms in social organization.Angiotensin-converting enzyme (ACE) is a zinc-dependent dicarboxypeptidase with two catalytic components, which has an important role in regulating blood pressure by converting angiotensin I to angiotensin II. ACE breaks down other peptides besides angiotensin I and has a variety of physiological effects together with renal growth and reproduction in men. ACE also acts on innate and acquired immune systems, by affecting macrophage and neutrophil function, and these outcomes are exacerbated due to the overexpression of ACE. Over expression of ACE in macrophages imposes antitumor and antimicrobial response, and it enhances the ability of neutrophil to produced super peroxide that has bactericidal effect. link= Tacrolimus molecular weight ACE is also known to contribute in the expression of Major Histocompatibility Complex (MHC) class I and MHC class II peptides through enzymatic alterations of these peptides. Apprehending the expression of ACE and its effects on myeloid cell (myelogenous cells) activity can be promising in therapeutic interventions, including treatment of infection and malignancy.
Erectile dysfunction (ED) is one of the extrahepatic manifestations of hepatitis C virus infection that greatly affects patients' quality of life. Unfortunately, some of the drugs used for HCV treatment may have a negative impact on the patient's erectile function such as the pegylated interferon. Currently, with the introduction of directacting antiviral drugs, there are scarce data in the literature about its potential impact on erectile function. In these settings, we aimed to assess the impact of sofosbuvir-based therapy on male erectile function.
This prospective interventional study was carried out in Benha University hospitals between January 2019 and May 2020. The study included all consecutive HCV patients with simultaneous ED coming to the hepatology outpatient clinic. Patients were divided into a study group who received sofosbuvir-based therapy (group A) or a control group who received silymarin therapy (group B). Tacrolimus molecular weight The International Index of Erectile Function-5 (IIEF-5) was used for assessment he degree of ED. Furthermore, sofosbuvir-based therapy may be associated with significant improvement in the patients' erectile function.Dementia and diabetes are the two major disorders that are linked at both biochemical and molecular levels which is due to the existing similarities between pancreatic beta-cells and neuronal cells at the transcription and translational levels. Both diseases have similar causative genes or factors and dementia is one of the advanced complications in about 50-52% of patients with type 2 diabetes mellitus (T2DM). link2 link2 Further, patients with T2DM are at a higher risk of neuronal degeneration and Alzheimer's disease (AD). Dementia, which is most common in AD, is associated with diminished insulin receptors by nearly 80%. The impairment in insulin signaling thus leads to the development of dementia and AD. Biochemical changes in 'tau' protein and amyloid-beta proteins, make them critical players in the formation of plaques in patients with dementia and AD. Here, we decode various cellular and molecular mechanisms associated with the development of dementia in patients with diabetes and AD.
Plant lectins has shown promising neuropharmacological activities in animal models.
This study evaluated the effect of Dioclea altissima seed lectin (DAL) on adult zebrafish behavior.
Zebrafish (n=6/group) were treated (i.p.; 20 µL) with DAL (0.025; 0.05 or 0.1 mg/mL), vehicle or diazepam (DZP) and submitted to several tests (open field, light/dark preference or novel tank). Flumazenil, pizotifen or granisetron were administered 15 min before DAL (0.05 mg/mL), and the animals were evaluated on light/dark preference test. It was also verified whether the DAL effect depended on its structural integrity and ability to interact with carbohydrates.
DAL decreased the locomotor activity of adult zebrafish (0.025; 0.05 or 0.1 mg/mL), increased the time spent in the upper region of the aquarium (0.025 mg/mL), and decreased the latency time of adult zebrafish to enter the upper region on the novel tank test. DAL (0.05 mg/mL) also increased their permanence in the light zone of the light/dark preference test. The effect of DAL was dependent on carbohydrate interaction and protein structure integrity and was prevented by pizotifen, granizetron and flumazenil.
DAL was found to have an anxiolytic-like effect mediated by the 5-HT and GABAergic receptors.

Gabapentin (GBP) is an FDA approved drug for the treatment of partial and secondary generalized seizures, apart from being used for diabetic neuropathic pain. GBP displays highly intricate mechanism of action and its inhibitory response in elevated antagonism of NMDA (N-methyl-D-aspartate receptor) receptor and thus, can be repurposed for controlling neuropathic pain.
Therefore, in the present study, we have selected hBCATc (human Pyridoxal 5'-phosphate dependent branched-chain aminotransferase cytosolic) gene that is highly expressed in neuropathic stressed conditions. link3 Thereafter, have analyzed the GBP as its competitive inhibitor by homology modeling, molecular docking, also predicting its structural alerts and pharmacokinetic suitability through ADMET. However, GBP was found to be a potential drug in controlling neuropathic pain, still it has certain critical pharmacokinetics limitations therefore, the need for its targeted delivery was required and the same was attained by designing a GBP loaded trandermal patch (TDP).
A suitable and equally efficacious GBP - TDP was developed by solvent evaporation method using PVP and HPMC in ratio of 21 as a polymer base for reservoir type of TDP. Also, PEG 400 was used as a plasticizer and PVA (4%) was taken for backing membrane preparation and then the optimized GBP-TDP was subjected for physical characterization, optimization and ex vivo release kinetics.
The results showed desired specifications with uneven and flaky surface appearance giving an avenue for controlled release of the drugs with 92.34 ± 1.43% of drug release in 10 h, further suggesting that GBP-TDP can be used as an effective tool against diabetic neuropathy pain.

It occurs due to the insufficient supply of oxygen-rich blood to the brain. It is a complex disease with multiple associated risk factors including smoking, alcoholism, age, sex, ethnicity, etc. link3 Calcium ions are known to play a vital role in cell death pathways, which is a ubiquitous intracellular messenger during and immediately after an ischemic period. Disruption in normal calcium hemostasis is known to be a major initiator and activator of the ischemic cell death pathway. Under Ischemic stroke conditions, glutamate is released from the neurons and glia which further activates the N-methyl-D-aspartate (NMDA) receptor and triggers the rapid translocation of Ca2+ from extracellular to intracellular spaces in cerebral tissues and vice versa. Various studies indicated that Ca2+ could have harmful effects on neurons under acute ischemic conditions. Mitochondrial dysfunction also contributes to delayed neuronal death, and it was established decades ago that massive calcium accumulation triggers mitochondrial damage. Elevated Ca2+ levels cause mitochondria to swell and release their contents. As a result oxidative stress and mitochondrial calcium accumulation activate mitochondrial permeability transition and lead to depolarization-coupled production of reactive oxygen species. This association between calcium levels and mitochondrial death suggests that elevated calcium levels might have a role in the neurological outcome in ischemic stroke. Previous studies have also reported that elevated Ca2+ levels play a role in the determination of infarct size, outcome, and recurrence of ischemic stroke. The current review has been compiled to understand the multidimensional role of altered Ca2+ levels in the initiation and alteration of neuronal death after ischemic attack. The underlying mechanisms understood till date have also been discussed.The article has been withdrawn at the request of the co-authors due to the death of the corresponding author (Dr. Aliev).
