The minimum inhibitory concentration (MIC) effect of Ɣ-PGA NP showed inhibitory effects of 0.2, 0.

Ultrasounds assisted one-pot oxidative desulfurization of model fuel using green synthesized aluminum terephthalate [MIL-53(Al)].

Oxidative desulfurization (ODS) is considered to be one of the most promising desulfurization processes as it is energy-efficient and requires mild operating conditions. In this study, a novel green synthesized Al- based metal-organic framework with high surface area has been synthesized hydrothermally using waste polyethylene terephthalate bottles (PET) as a source of terephthalic acid as an organic linker. The prepared Al based MOF have been characterized using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscopy (TEM).

COVID-19-induced multisystem inflammatory syndrome in a child with Wilson disease: a case report.

Background: Infection with coronavirus disease 2019 (COVID-19) can progress to the multisystem inflammatory syndrome in children (MIS-C). Patients with liver cirrhosis are at increased risk of complications.

Case Presentation: We report on a 13-year-old Wilson's disease patient who was referred for liver transplantation because of rapid deterioration in his hepatic condition.

Ameliorating effects of probiotics on alterations in iron homeostasis and inflammation in COVID-19.

Introduction: The coronavirus disease (COVID-19) is caused by the severe acute syndrome coronavirus-2 (SARS-COV-2) and still threatens human life. This pandemic is still causing increased mortality throughout the world. Many recent studies have been conducted to discover the pathophysiology of this virus.

Dietary conjugated linoleic acid and medium-chain triglycerides for obesity management.

Obesity is considered a serious global health issue. Patients have been predisposed to comorbidities such as dyslipidemia, cardiovascular diseases, diabetes, cancers, and osteoarthritis. Certain fats in the diet have been linked with an increase in obesity, such as saturated and trans-fats.

Assessment of sexual functions in male patients with obstructive sleep apnea.

Purpose: Obstructive sleep apnea is characterized by repetitive cessation of breathing during sleep. It affects different aspects of sexuality. We aimed to assess male sexual function & risk factors in obstructive sleep apnea patients.

Effect of the Morphology of Tungsten Oxide Embedded in Sodium Alginate/Polyvinylpyrrolidone Composite Beads on the Photocatalytic Degradation of Methylene Blue Dye Solution.

Tungsten oxide nanostructures were modified by oxygen vacancies through hydrothermal treatment. Both the crystalline structure and morphological appearance were completely changed. Spherical WO·HO was prepared from tungstic acid solution by aging at room temperature, while rod-like WO·0.

The Impact of Thyme and Rosemary on Prevention of Osteoporosis in Rats.

Osteoporosis poses an important public health problem which affects millions of people worldwide. There is a direct link between calcium deficiency in diet and induction of osteoporosis and bone loss. The current study was conducted to evaluate the protective effect of thyme ( L.

Dietary antioxidant for disease prevention corroborated by the Nrf2 pathway.

Dietary antioxidants are widely distributed in various types of our food. They are strongly associated with reduced risk of many chronic diseases such as atherosclerosis, cancer, and Alzheimer's diseases. They include vitamins such as vitamins A, E, C, and carotenoids.

Potential Role of L-Arginine and Vitamin E Against Bone Loss Induced by Nano-Zinc Oxide in Rats.

The purpose of this study was to illustrate the effects of zinc oxide nanoparticles (ZnO-NPs) administration on bone turnover and bone resorbing agents in rats and how L-arginine (L-arg) or vitamin E (vit E) co-administrations might affect them. Fasting rats were randomly divided into four groups (n = 10): G1-normal healthy animals; G2-ZnO-NPs-exposed rats (600 mg/kg1/day); G3-ZnO-NPs-exposed rats co-administrated L-arg (200 mg/kg1/day); G4-ZnO-NPs-exposed rats co-administrated vit E (200 mg/kg1/day). The ingredients were orally administered daily.

Fate and transport of monensin in the presence of nonionic surfactant Brij35 in soil.

As fresh water is a limited resource in many parts of the world, the use of wastewater for irrigation has become an important alternative. Therefore, many countries facing a water deficit, use partially treated, or even untreated, wastewater. This may increase the input of many contaminants into the environment.

Sorption/desorption behavior of oxytetracycline and sulfachloropyridazine in the soil water surfactant system.

Sorption/desorption of antibiotics, oxytetracycline (OTC), and sulfachloropyridazine (SCP) was investigated in the presence of a nonionic surfactant Brij35. Batch sorption experiments indicated that Freundlich equation fits sorption isotherms well for OTC. The sorption coefficients, KF, values were computed as 23.

Hepatoprotective, antioxidant, and ameliorative effects of ginger (Zingiber officinale Roscoe) and vitamin E in acetaminophen treated rats.

Ginger is a remedy known to possess a number of pharmacological properties. This study investigated efficacy of ginger pretreatment in alleviating acetaminophen-induced acute hepatotoxicity in rats. Rats were divided into six groups; negative control, acetaminophen (APAP) (600 mg/kg single intraperitoneal injection); vitamin E (75 mg/kg), ginger (100 mg/kg), vitamin E + APAP, and ginger + APAP.

Effect of nonionic surfactant Brij 35 on the fate and transport of oxytetracycline antibiotic in soil.

In many parts of the world, river water is used for irrigation. Treated, partially treated, and even untreated water from wastewater treatment plants is discharged directly into rivers, thereby degrading the quality of the water. Consequently, irrigation water may contain surfactants which may affect the fate and transport of chemicals such as pesticides and antibiotics in agricultural soils.

Proposed remedies for some developmental disorders.

Developmental disorders (DDs) are important leading cause of disability in developed countries and also in the United States. DDs are a group of individual conditions that result from abnormal nervous system development and cause altered function. They can begin at any time from prenatal to 22 years of age and the disability usually presents itself throughout a person's life time.

Immunohistochemical expression of ezrin in cutaneous basal and squamous cell carcinomas.

Ezrin is a member of the ezrin-radixin-moesin family of proteins, which link the actin-containing cytoskeleton to the plasma membrane. Overexpression of ezrin protein is correlated with the metastatic potential in several cancers. Little is known about the distribution of ezrin in normal epidermis and nonmelanoma skin cancer; therefore, in the current study, we examined the immunohistochemical expression of ezrin in normal skin (10 biopsies) and epithelial skin tumors (25 basal cell carcinoma [BCC] and 20 squamous cell carcinoma [SCC]).

Objective: To assess homocysteine, folic acid and vitamin B12, trace element levels and oxidant/antioxidant status in Down syndrome (DS) mothers and children.

Design And Methods: 42 mothers with previous history of bearing DS baby with karyotypically confirmed full trisomy 21 were included. 48 healthy mothers with their healthy children were considered as control.

Effect of Ruta graveolens L. and Euphorbia peplus L. anti-inflammatory extracts on nutritional status of rats and the safety of their use.

A significant increase in body weight with remarkable increase in total food intake and significant increase in protein efficiency ratio were observed following oral administration of R. graveolens ether extract (500 mg/kg body wt) to growing rats for 3 weeks. Serum albumin was significantly decreased after administration of declofenac (15 mg/kg body wt).
