4-Amidino-pyridinium hexa-chlorido-stannate(IV) dihydrate.

In the title hydrated mol-ecular salt {systematic name: 4-[amino-(iminium-yl)meth-yl]pyridin-1-ium hexa-chlorido-stannate(IV) dihydrate}, (CHN)[SnCl]·2HO, the tin atom lies on a crystallographic inversion centre and the organic cation shows whole-mol-ecule disorder. Numerous N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds link the components in the crystal.

Bis(2-amino-3,5-di-chloro-pyridinium) hexa-chlorido-stannate(IV) dihydrate.

The title hybrid compound, (CHNCl)[SnCl]·2HO, was synthesized and its structure was identified by single-crystal X-ray diffraction. The structure is non-polymeric (0D) in terms of containing isolated [SnCl] polyhedra. The special position (0,0,0) of the Sn atom in the crystal structure gives rise to a stacking structure with alternating cationic and anionic layers parallel to (001).

Metabolic syndrome screening in adolescents: New scores AI_METS based on artificial intelligence techniques.

Background And Aims: Metabolic syndrome (MetS) definitions in adolescents based on the percentiles of its components are rather complicated to use in clinical practice. The aim of this study was to test the validity of artificial intelligence (AI)-based scores (AI_METS) that do not use these percentiles for MetS screening for adolescents.

Methods And Results: This study included 1086 adolescents aged 12 to 18.

Emergent and Neglected Equine Filariosis in Egypt: Species Diversity and Host Immune Response.

Equine filariosis (EF) is a neglected vector-borne disease caused by nematode species belonging to the Onchocercidae and Setariidae families. Aside from their zoonotic potential, some species are responsible for serious health problems in equids worldwide, leading to significant economic difficulties. Here, we molecularly investigated equine blood samples (320 horses and 109 donkeys from Egypt) and four adult worms isolated from the peritoneal cavity of 5 out of the 94 slaughtered donkeys.

Removal of the industrial azo dye crystal violet using a natural clay: Characterization, kinetic modeling, and RSM optimization.

Natural clay (NC) was employed as a natural adsorbent for the elimination of an azo dye Crystal Violet (CV) from aqueous media. The characterization of the clay was performed by X-ray diffractometry (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) equipped with an X-ray energy dispersion spectrometer (EDS) and Brunauer-Emmett-Teller (BET) specific surface area analysis. The Box-Behnken design (BBD) was used as a powerful tool to determine the stationary points of the main independent factors: initial CV concentration, initial pH, temperature, and adsorbent dose on the adsorption efficiency.

Inborn Errors of Immunity in Algerian Children and Adults: A Single-Center Experience Over a Period of 13 Years (2008-2021).

Background: Inborn errors of immunity (IEI) predispose patients to various infectious and non-infectious complications. Thanks to the development and expanding use of flow cytometry and increased awareness, the diagnostic rate of IEI has markedly increased in Algeria the last decade.

Genetic and geographical delineation of zoonotic vector-borne helminths of canids.

Several zoonotic vector-borne helminths (VBHs) infesting canids cause serious veterinary and medical diseases worldwide. Increasing the knowledge about their genetic structures is pivotal to identify them and therefore to settle effective surveillance and control measures. To overcome the limitation due to the heterogeneity of large DNA sequence-datasets used for their genetic characterization, available cytochrome c oxidase subunit 1 (cox1) (n = 546) and the 12S rRNA (n = 280) sequences were examined using combined bioinformatic approach (i.

Assessment of heavy metal pollution in urban and peri-urban soil of Setif city (High Plains, eastern Algeria).

Heavy metal pollution is a challenging concern that threatens the soil environment and human health worldwide. The purpose of this work is to assess the heavy metals (Cr, Cu, Zn, and Pb) pollution in the urban and peri-urban soils in and around Setif city, eastern Algeria. The work combines chemical analysis of thirty-six soil samples, statistical valuation and interpretation of chemical data and pollution indices (geoaccumulation index, pollution index, and integrated pollution index) with thematic mapping.

Lean 4.0 tools and technologies to improve companies' maturity level: the COVID-19 context.

The global pandemic triggered by the new COVID-19 led to severe limitations in daily life, both private and professional. Almost all companies have been affected in one way or another. The COVID-19 crisis imposed new challenges for enterprises.

Optoacoustic imaging and potential applications of raster-scan optoacoustic mesoscopy in dermatology.

Optoacoustic imaging (OAI) is a hybrid imaging modality that integrates the benefits of optical contrast and ultrasound detection. Raster-scan optoacoustic mesoscopy (RSOM) is an emerging OAI method that provides information about several dermatological conditions' structural, functional, and molecular features. We searched PubMed and Google Scholar databases through September 2021 for contributions relevant to OAI in the English language.

CYP2E1 inhibition and NF_κB Signaling Pathway are Involved in the Protective Molecular Effect of against Acetaminophen-induced acute Hepatotoxicity in Rats.

The present study aimed to estimate the potential and the molecular mechanism of the hydro-ethanolic extract of against acetaminophen (AC) induced hepatotoxicity. Four groups of female Wistar rats (n=6) was formed to study the hepatoprotective effect of extract against acetaminophen overdose (2 g/kg): Groups N and AC received orally tap water for 03 days and Groups + AC and N+: received orally extract (400 mg/kg). After 1hour (h) of the last dose administered, the paracetamol solution (2 g/kg) is administered orally for group AC and + AC.

Enhanced degradation of 2,6-dimethylphenol by photocatalytic systems using TiO assisted with HO and Fe(III).

In this study, several photocatalytic degradation systems were investigated using 2,6-dimethylphenol (2,6-DMP) as a model compound.

Lamb's infections raised in a steppic region and their impacts on clinical indicators (FAMACHA and Disco).

A total of 290 lambs in 29 small flocks were studied from October to January 2020, conducted in a semi-extensive rearing system. The objective was to identify by the microscopic morphology of oocysts the species that infect lambs in a steppe region of eastern Algeria, as well as to evaluate on these parasites two clinical indicators of diarrhea (Disco) and anemia (FAMACHA©) used in targeted selective treatments against gastrointestinal nematodes (GIN). This present work completes the previous evaluations carried out in steppe conditions in our laboratory on GIN and cestodes.

This retrospective study aimed to investigate the EGFR mutation status in Algerian NSCLC patients and its association with clinicopathological features.

Physics in Africa.

Africa tends to be isolated and sometimes forgotten when it comes to scientific research and in particular physics. But the region has great potential, being home to the youngest population in the world, and despite a variety of issues, there has been steady, albeit uneven progress towards establishing a scientific infrastructure. Ten African researchers discuss the diverse challenges and opportunities faced by physicists across the continent.

Mechanistic basis of breast cancer resistance protein inhibition by new indeno[1,2-b]indoles.

The ATP-binding cassette transporter ABCG2 mediates the efflux of several chemotherapeutic drugs, contributing to the development of multidrug resistance (MDR) in many cancers. The most promising strategy to overcome ABCG2-mediated MDR is the use of specific inhibitors. Despite many efforts, the identification of new potent and specific ABCG2 inhibitors remains urgent.
