Neuroinflammation can be triggered by a high-fat/high-fructose diet (HFFD), and CD36 may be an underlying mechanism. Lauric acid (LA), the major fatty acid in coconut oil, and resveratrol, the plant-based polyphenolic compound, may exert anti-inflammatory effects. Therefore, this study investigated the possible effects of LA and resveratrol on diet-induced neuroinflammation and CD36.

: Transverse maxillary deficiency is an important maxillary anomaly that is very common in society and remains current in orthodontics. The maxillary expansion has been used in treatment for a long time. While maxillary expansion can be performed with rapid maxillary expansion in young adults, it is performed with surgically assisted rapid maxillary expansion (SARME) in individuals who have reached skeletal maturity.

  • Gelsolin (GSN) has two forms: plasma (pGSN) and cytosolic (cGSN), which are linked to various diseases.
  • The study examined how chronic sustained hypoxia (CSH) impacts GSN levels and HIF-1 in rats, alongside measuring apoptosis and redox status.
  • Findings revealed that HIF-1α significantly increased in severe hypoxia, while pGSN decreased in both plasma and tissue, and cGSN levels increased in lung tissue, indicating a potential protective mechanism against cell damage.

  • Cisplatin is an anticancer drug that causes liver damage, and this study investigates the protective effects of Myricetin, a flavonoid, against that damage.
  • The experiment involved 32 male rats divided into four groups to assess the histological changes and biochemical markers related to liver health.
  • Results showed that Myricetin improved liver tissue structure and reduced inflammatory markers and liver enzyme levels associated with Cisplatin toxicity, suggesting it may help mitigate the drug's harmful effects.

Objectives: The study aimed to examine the histopathological and biomechanical effects of papaverine administered intraperitoneally and locally on Achilles tendon healing in a rat model.

Materials And Methods: Forty-eight adult male Sprague-Dawley rats (range, 300 to 400 g) were used in this study conducted between October and November 2022. The rats were divided into three groups, with each group further subdivided into two for sacrifice on either the 15 (early period) or 30 (late period) day after surgery.

Article Synopsis
  • - This study investigates the cardiotoxic effects of methotrexate (MTX), a chemotherapy drug, and the potential protective role of vitamin B12 in mitigating this toxicity in rats.
  • - Rats were divided into four groups: a control group, a vitamin B12 group, an MTX group, and a combined MTX and vitamin B12 group, with various biomarkers and tissue expressions evaluated to assess heart health.
  • - The results showed MTX caused significant negative changes in heart-related factors and that vitamin B12 effectively normalized these changes, emphasizing the importance of vitamin B12 supplementation during MTX treatment.

Purpose: We aimed to explore the performance of diffusion-tensor imaging (DTI) and apparent diffusion coefficient (ADC) parameters in evaluating disease-free survival (DFS) and overall survival (OS) in patients with invasive breast cancer.

Material And Methods: A total of 49 women with invasive breast cancer who were diagnosed between 2017 and 2022 were included. All patients underwent breast magnetic resonance imaging (MRI) with DTI and diffusion-weighted imaging (DWI) features, with examiners blinded to the clinical data.

  • - Quinoa is a nutritious, gluten-free pseudocereal, and this study examined its effects on glucose homeostasis in rats fed a cafeteria diet that led to obesity.
  • - Rats were divided into four diet groups: control chow, quinoa, cafeteria diet, and a combination of quinoa and cafeteria diet, with varied impacts on body weight, insulin levels, and liver health observed among groups after 15 weeks.
  • - The study concluded that quinoa may help prevent obesity and related metabolic issues like glucose intolerance and liver resistance, suggesting its potential as a functional food.

This study aimed to investigate the protective effect of melatonin against the acute toxicity of cisplatin in ocular tissues. The eyes of 40 rats were divided into 4 groups: Control group (10 rats), Melatonin (Mel) group (10 rats), Cisplatin (Cis) group (10 rats), Melatonin (Mel) + Cisplatin (Cis) group (10 rats). Retina, cornea, and ciliary body tissues were examined after hematoxylin-eosin staining of sections obtained from the eyes and were scored for disorganization and degeneration.

  • The study explores the use of machine learning to predict joint moments during gait in patients with cerebral palsy (CP) and typically developed (TD) individuals, which can aid clinical decision-making.
  • It utilizes one-dimensional convolutional neural networks (CNN) to analyze kinematic data—trunk, pelvis, hip, knee, and ankle movement—and predicts moments like dorsi-plantar flexion and hip flexion-extension.
  • Although the model shows promise, with prediction errors lower for TD individuals compared to CP patients, the current accuracy limits its immediate clinical utility.

Background: Scarless healing comprises the ultimate goal after an injury. Since tendon healing results in a fibrotic scar, an injured tendon can never regain the mechanical potential and strength of its uninjured form. A wide variety of studies focus on the tendon healing with an absent or minimal peritendinous adhesions.

  • Doxorubicin (DOX) is an effective cancer drug but causes kidney damage as a side effect, prompting research on protective agents.
  • Thymoquinone (THQ), a natural compound with antioxidant and anti-inflammatory properties, was tested on rats to see if it could mitigate DOX-induced kidney toxicity.
  • Results showed that THQ significantly reduced kidney damage and improved kidney function by lowering markers of inflammation and apoptosis compared to the DOX-only group.

PURPOSE This article will examine the usefulness of diffusion tensor imaging (DTI) and diffusion-weighted imaging (DWI) on the assessment of axillary lymph nodes (ALN) of breast cancer patients. METHODS Axillary lymph nodes in 66 breast cancer patients were examined by DTI and DWI, and the largest lymph node with increased cortical thickness in axilla was selected. Morphological features, apparent diffusion coefficient (ADC), volume anisotropy, and fractional anisotropy values were measured by using a special software.
