Adventitious bursitis is an inflammatory condition affecting bursae. Distinct from primary or infectious bursitis, adventitious bursitis typically develops secondary to conditions such as rheumatoid arthritis, gout, or repetitive joint overuse. The resulting inflammation can lead to pain, swelling, and restricted mobility, significantly impacting patients' quality of life.

This study aimed to enhance inulinase production from agricultural biomass pretreated with deep eutectic solvents (DES) using Aspergillus niger A42 (ATCC 204447). Barley husk (BH), wheat bran (WB), and oat husk (OH) were selected as substrates and were pretreated using different molar ratios of choline chloride: glycerol (ChCl: Gly) and choline chloride: acetic acid (ChCl: AA). DES pretreatment was followed by dilute sulfuric acid hydrolysis.

Objective: Early-Onset Scoliosis Self-Report Questionnaire (EOSQ-SELF) is a recently developed self-reported questionnaire based on the widely adopted Early-Onset Scoliosis Questionnaire and evaluates health-related quality of life in children with early-onset scoliosis over 8 years of age. To date, the questionnaire does not have a validated version in Turkish. The aim of this study was to translate EOSQ-SELF into Turkish and evaluate its reliability and validity.

Natural fiber-reinforced composites are composite materials composed of natural fibers, such as plant fibers and synthetic biopolymers. These environmentally friendly composites are biodegradable, renewable, cheap, lightweight, and low-density, attracting attention as eco-friendly alternatives to synthetic fiber-reinforced composites. In this study, natural fiber-reinforced polymer foam core layered composites were produced for the automotive industry.

: Cyclophosphamide (CP) is widely used for treating various cancers and autoimmune diseases, but it causes damage to reproductive organs due to oxidative stress (OS) and inflammation. Boric acid (BA) has antioxidant properties that may help reduce OS, which is critical for preserving uterine functionality, particularly for cancer patients considering pregnancy after cryopreservation. This study aimed to determine whether BA could diminish CP-induced toxicity in the uterus and fallopian tubes (FT) using CP-induced toxicity in a rat model.

Osteoporosis is a common disease of the skeletal system that increases the risk of fracture. The prevalence of osteoporosis has been increasing as the aging population increases, affecting more than 200 million people worldwide. This study aimed to shed light on the clinical impact of osteoporosis on women's health and quality of life by evaluating the prevalence and risk factors for this disease among postmenopausal women, using a 10-year dataset from a tertiary center.

: This case study investigates the effect of a five-session whole-body cryostimulation (WBC) cycle on a 55-year-old female patient with cerebral palsy (CP) and lower limb spasticity (LLS) with a typical diplegic gait pattern. CP is a common physical disability characterized by motor impairments, including spasticity, which significantly impacts mobility and quality of life. The current treatments for spasticity often have limited efficacy and considerable side effects, making alternative therapies like WBC an area of interest.

This article explores the life and work of Dr Caroline F. Hamilton, one of the pioneering female physicians sent from the USA to the Ottoman Empire in the late 19th century. Over a career spanning three decades, Hamilton provided critical medical care, especially to women, at the Azariah Smith Memorial Hospital in Aintab, overcoming legal, cultural, and political obstacles to become one of the first women licensed to practise medicine in the region.

The invasion and metastasis of cancer cells transform localized cancers into systemic and life-threatening diseases, posing one of the most significant challenges in cancer treatment. This study tested the hypothesis that combined treatment with Caffeic acid (CA) and metformin (MTF) could inhibit or reduce effective signaling pathways involved in the proliferation, survival, and metastasis of MCF-7 breast cancer cells. Anti-proliferation analysis determined the IC50 values for MTF (4.

Mortality rate of the crush victims in the Marmara earthquake of August 1999 was compared with the conclusions arrived after making thermodynamic assessment of the data acquired in the previous earthquakes. Entropic age concept was found very helpful while assessing the data. Mortality rate in the age group of 0-9 years old crush victims was 0 because the basal metabolic rate (BMR) of these children was low.

This article discusses infection, a zoonotic parasite that lives in the liver bile ducts. A 31-year-old female patient was diagnosed with symptoms such as nausea, increased liver enzymes, and right upper quadrant pain for about a year. The parasite was detected in the common bile duct by Endoscopic Ultrasound (EUS) and removed by Endoscopic Retrograde Cholangio Pancreatography (ERCP).

Background And Objective: Cancer's complex and multifaceted nature makes it challenging to identify unique molecular and pathophysiological signatures, thereby hindering the development of effective therapies. This paper presents a novel fractal-fractional cancer model to study the complex interplay among stem cells, effectors cells, and tumor cells in the presence and absence of chemotherapy. The cancer model with effective treatment through chemotherapy drugs is considered and discussed in detail.

Over the past few years, nanoplasmonic biosensors have gained widespread interest for early diagnosis of diseases thanks to their simple design, low detection limit down to the biomolecule level, high sensitivity to even small molecules, cost-effectiveness, and potential for miniaturization, to name but a few benefits. These intrinsic natures of the technology make it the perfect solution for compact and portable designs that combine sampling, analysis, and measurement into a miniaturized chip. This review summarizes applications, theoretical modeling, and research on portable nanoplasmonic biosensor designs.

Currently, the increasing use of nickel metal-organic frameworks (Ni-MOF) and nickel oxide nanoparticles (NiO NPs) has raised concerns regarding their potential environmental impact on wastewater treatment systems. Herein, the responses of aerobic granular sludge (AGS) and algal-bacterial aerobic granular sludge (AB-AGS) to Ni-MOF and NiO NPs were investigated. The results showed that Ni-MOF concentrations of 50, 100, and 200 mg/L significantly reduced nutrient removal in both systems, particularly affecting ammonia, nitrite, and phosphorus removal, while denitrification processes remained stable.
