Hidden in the sand: Phylogenomics unravel an unexpected evolutionary history for the desert-adapted vipers of the genus Cerastes.

The desert vipers of the genus Cerastes are a small clade of medically important venomous snakes within the family Viperidae. According to published morphological and molecular studies, the group is comprised by four species: two morphologically similar and phylogenetically sister taxa, the African horned viper (Cerastes cerastes) and the Arabian horned viper (Cerastes gasperettii); a more distantly related species, the Saharan sand viper (Cerastes vipera), and the enigmatic Böhme's sand viper (Cerastes boehmei), only known from a single specimen in captivity allegedly captured in Central Tunisia. In this study, we sequenced one mitochondrial marker (COI) as well as genome-wide data (ddRAD sequencing) from 28 and 41 samples, respectively, covering the entire distribution range of the genus to explore the population genomics, phylogenomic relationships and introgression patterns within the genus Cerastes.

Strategies to improve the stability of amorphous solid dispersions in view of the hot melt extrusion (HME) method.

Oral administration of drugs is preferred over other routes for several reasons: it is non-invasive, easy to administer, and easy to store. However, drug formulation for oral administration is often hindered by the drug's poor solubility, which limits its bioavailability and reduces its commercial value. As a solution, amorphous solid dispersion (ASD) was introduced as a drug formulation method that improves drug solubility by changing the molecular structure of the drugs from crystalline to amorphous.

Role of Polyphenols, Their Nano-formulations, and Biomaterials in Diabetic Wound Healing.

A diabetic wound is one of the major complications arising from hyperglycemia, neuropathy, and oxidative stress in diabetic patients. Finding effective treatments for diabetic wounds has been difficult owing to the complex pathophysiology of diabetic wound environments. Chronic wounds are notoriously difficult to treat with conventional wound care methods.

Prevalence of occult hepatitis B virus infection in Egypt: a systematic review with meta-analysis.

Background: Occult hepatitis B virus (HBV) infection (OBI) is a major public health problem. The clinical importance of OBI stems from the fact that it can be transmitted to healthy individuals at extremely low viral load levels. Additionally, immunosuppression has the potential to trigger viral replication, which can result in life-threatening liver decompensation.

Hybrid Prosthesis versus Overdenture: Effect of BioHPP Prosthetic Design Rehabilitating Edentulous Mandible.

Aim: To compare the BioHPP (biocompatible high-performance polymer) as a substructure for the hybrid prosthesis versus the BioHPP bar supporting and retaining implant overdenture by radiographic evaluation to identify bone height alteration around the implants and to evaluate satisfaction based on visual analoge scale questionnaire.

A review on taste masked multiparticulate dosage forms for paediatric.

Taste refers to those sensations perceived through taste buds on the tongue and oral cavity. The unpleasant taste of drugs leads to the refusal of taking the medicine in the paediatric population. It is widely known that a pharmaceutical product's general acceptability is the result of numerous contributing components such as swallowability, palatability (taste, flavour, texture, and mouthfeel), appearance, ease of administration, and patient characteristics.
