Exploring Azithromycin's Neuroprotective Role in Traumatic Brain Injury: Insights into Cognitive and Motor Recovery and Neuroinflammatory Modulation.

Background: Traumatic brain injury (TBI) is a leading cause of mortality worldwide and often results in substantial cognitive, motor, and psychological impairments, triggering oxidative stress, neuroinflammation, and neurodegeneration. This study examined the neuroprotective effects of azithromycin (AZI) in TBI.

Methods: TBI was induced in rats using the weight-drop method.

Gum Resin Mitigates Renal Toxicity: Role of TNF-α, Interleukins, TGF-β, and Lipid Peroxidation.

Being a central organ in homeostasis and maintaining the health of the biological system, kidneys are exposed to variable toxicants. Long-term exposure to nephrotoxic molecules causes chronic renal damage that causes fibrosis and loss of function. Such damage can be initiated by oxidative stress which provokes inflammation.

Decoding Clozapine-Induced Agranulocytosis: Unraveling Interactions and Mitigation Strategies.

Agranulocytosis represents a severe complication associated with the administration of clozapine. Clozapine is an antipsychotic medication that has demonstrated substantial efficacy in remediating refractory schizophrenia and various other psychiatric disorders. Nonetheless, it is crucial to monitor patients for neutropenia regularly during clozapine therapy.

Sitagliptin ameliorates L-arginine-induced acute pancreatitis via modulating inflammatory cytokines expression and combating oxidative stress.

Background: Acute pancreatitis (AP) is an inflammatory condition that resolves spontaneously, but occasionally, develops into systemic inflammation, organ failure and mortality. Oxidative stress and activation of inflammatory pathways represent major players in AP pathogenesis. Current management of AP relies on attenuating injuries to the pancreas and putting the inflammatory process under control.

Prescription patterns of quetiapine for multiple drug abuse, depression, and psychosis: A retrospective study.

Background: Quetiapine is an atypical antipsychotic prescribed for schizophrenia, bipolar disorder, multiple drug abuse (MDA), generalized anxiety disorder, severe depression, dementia, and mood disorders. Prescription of quetiapine varies according to use, with side effects increasingly reported with higher doses. Many previous case reports highlighted the misuse of the drug.

Evaluation of Sleep Behavior and the Use of Sleep Aids among Adults Living in Saudi Arabia: A Cross-Sectional Study.

A negative attitude toward sleep has greatly affected sleep habits. In addition to contributing to physical and metabolic disorders, poor sleep quality may cause emotional disturbances. This study aimed to measure sleep behavior and factors contributing to poor sleep quality in the Madinah region, Saudi Arabia.

Physical Characteristics, Blue-Green Band Emission and Photocatalytic Activity of Au-Decorated ZnO Quantum Dots-Based Thick Films Prepared Using the Doctor Blade Technique.

Nanoscale ZnO is a vital semiconductor material whose versatility can be enhanced by sensitizing it with metals, especially noble metals, such as gold (Au). ZnO quantum dots were prepared via a simple co-precipitation technique using 2-methoxy ethanol as the solvent and KOH as the pH regulator for hydrolysis. The synthesized ZnO quantum dots were deposited onto glass slides using a simple doctor blade technique.

Development of Perovskite (MACl)FAMAPb(IBr) Solar Cells via n-Octylammonium Iodide Surface Passivation.

The influence of n-octylammonium iodide (OAI, passive layer) on the types of phases formed in a (MACl)FAMAPb(IBr) perovskite film was studied using X-ray diffraction. Using UV spectrophotometric techniques, it was determined how varied OAI additive layer ratios affected the linear and nonlinear optical characteristics of glass substrates/FTO/compact TiO/mesoporous TiO/(MACl)FAMAPb(IBr) films. All films' direct optical bandgap energies were determined to be 1.

IL-6 at the center of cytokine storm: Circulating inflammation mediators as biomarkers in hospitalized COVID-19 patients.

Introduction: The management of hospitalized COVID-19 patients depends largely on controlling the intensified inflammatory response known as the cytokine storm. Candidate inflammatory cytokines can serve as new biomarkers for the management of hospitalized COVID-19 patients.

Methods: Patients (80) were recruited into three groups: room air (RA), oxygen (OX) and mechanical ventilator (MV).

Alpha-Mangostin ameliorates acute kidney injury via modifying levels of circulating TNF-α and IL-6 in glycerol-induced rhabdomyolysis animal model.

Alpha mangostin (AM), isolated from G. mangostana, showed beneficial effects in several disorders due to its antioxidant and anti-inflammatory properties. Acute kidney injury (AKI) due to different etiologies can develop into severe complications, resulting in high mortality rates.

Aleppo galls alleviate paracetamol-induced hepatotoxicity and tissue damage: an experimental study.

Background: Acute paracetamol toxicity is a common and potentially life-threatening emergency causing liver failure that may necessitate liver transplantation. Unfortunately, current therapies are still defective.

Objectives: To investigate the protective effects exerted by Aleppo galls (Quercus infectoria Olivier) extract against acute paracetamol toxicity in mice.

Acute paracetamol toxicity-induced inflammatory and oxidative effects are relieved by Aleppo galls: a novel experimental study.

Background: Paracetamol (acetaminophen) is an over-the-counter non-steroidal anti-inflammatory drug that may cause acute toxic overdosage particularly in neuropsychiatric patients. Paracetamol is also very commonly prescribed as an analgesic and antipyretic agent. Paracetamol toxicity causes decreased reduced glutathione and oxidative tissue damage.

Developmental treatments with Δ- tetrahydrocannabinol and the MAGL inhibitor JZL184 persistently alter adult cocaine conditioning in contrasting ways.

Using a songbird, zebra finches, as a developmental drug abuse model we found previously that cannabinoid agonists administered during the sensorimotor period of vocal learning (50-75 days of age) persistently alter song patterns and cocaine responsiveness in adulthood. However, these effects were not produced in adults exposed to similar treatment regimens. Currently, we have used the MAGL inhibitor, JZL184, to test whether enhanced endocannabinoid signaling may similarly alter cocaine responsiveness.

Malignant Diffuse-Type Tenosynovial Giant Cell Tumor in the Subcutaneous Tissue of the Midthigh: A Report of a Rare Tumor in an Unusual Location.

Malignant TS-GCT is an extremely rare and aggressive tumor with only few cases published in the literature, due to the small number of cases is not completely understood and is diagnostically challenging. Although surgical treatment is the primary treatment modality, there is no consensus regarding adjuvant treatment. Regardless of mode of treatment, the tumor still caries unfavorable prognosis.

Carpal Tunnel Syndrome Caused by A Fibrolipomatous Hamartoma of the Median Nerve.

Fibrolipomatous hamartoma (FLH) of the nerve (also known as perineural lipoma, neural fibrolipoma, or lipomatosis of the nerve) is a well-known, rare benign lesion that can affect any peripheral nerve, resulting in significant enlargement of the involved nerve with fibrofatty infiltration. Although it is most commonly involving the median nerve, other peripheral nerves can be also involved. Being familiar with the pathognomonic characteristics on different imaging modalities and the association of this entity with macrodactyly help reach the diagnosis, avoid putting the patient at risk of an invasive procedure, and can guide management.

Delta-9-THC exposure during zebra finch sensorimotor vocal learning increases cocaine reinforcement in adulthood.

Zebra finches are songbirds that learn vocal patterns during a sensitive period of development that approximates adolescence. Exposure of these animals to a cannabinoid agonist during their period of sensorimotor vocal learning alters song patterns produced in adulthood. Thus, songbirds have unique value in studying developmental effects of drug exposure on a naturally learned behavior.
