Molecular diversity and genetic potential of new maize inbred lines across varying sowing conditions in arid environment.

Developing high-yielding and resilient maize hybrids is essential to ensure its sustainable production with the ongoing challenges of considerable shifts in global climate. This study aimed to explore genetic diversity among exotic and local maize inbred lines, evaluate their combining ability, understand the genetic mechanisms influencing ear characteristics and grain yield, and identify superior hybrids suited for timely and late sowing conditions. Seven local and exotic maize inbred lines were genotyped using SSR (Simple Sequence Repeat) markers to assess their genetic diversity.

Investigating the Potential of Ufasomes Laden with Nintedanib as an Optimized Targeted Lung Nanoparadigm for Accentuated Tackling of Idiopathic Pulmonary Fibrosis.

: Idiopathic pulmonary fibrosis (IPF) is a prevalent interstitial lung disease that typically progresses gradually, leading to respiratory failure and ultimately death. IPF can be treated with the tyrosine kinase inhibitor, nintedanib (NTD), owing to its anti-fibrotic properties, which ameliorate the impairment of lung function. This study aimed to formulate, optimize, and assess NTD-loaded ufasomes (NTD-UFSs) as a nanosystem for its pulmonary targeting to snowball the bioavailability and therapeutic efficacy of the drug.

Optimization and Appraisal of Nintedanib-Loaded Mixed Polymeric Micelles as a Potential Nanovector for Non-Invasive Pulmonary Fibrosis Mitigation.

Novel in situ gelling vaginal sponges of sildenafil citrate-based cubosomes for uterine targeting.

Sildenafil citrate (SIL), a type 5-specific phosphodiesterase inhibitor, demonstrates valuable results in the management of infertility in women; however, the absence of vaginal dosage form in addition to the associated oral adverse effects minimize its clinical performance. The present study is concerned with SIL uterine targeting following intravaginal administration via optimization of cubosomal in situ gelling sponges (CIS). An emulsification method was employed for preparation of cubosomal dispersions incorporating glyceryl monooleate as a lipid phase and poloxamer 407 as a surfactant with or without polyvinyl alcohol as a stabilizer.

Modifiers of the effect of maternal multiple micronutrient supplementation on stillbirth, birth outcomes, and infant mortality: a meta-analysis of individual patient data from 17 randomised trials in low-income and middle-income countries.

First report on Ambisome-associated allergic reaction in two Sudanese leishmaniasis patients.

Post kala-azar dermal leishmaniasis (PKDL) and mucosal leishmaniasis (ML) are serious clinical forms of leishmaniasis caused by Leishmania donovani parasites in Sudan. Although pentavalent antimonys are used as the first line of treatment of all clinical forms of leishmaniasis, persistent PKDL and ML patients are treated with liposomal amphotericin B (Ambisome) as a second-line drug. In this work, we report the development of allergic reactions by a PKDL and a ML Sudanese patient to Ambisome.
