Background: Spontaneous reperfusion (SR) occurring before primary percutaneous coronary intervention (PPCI) can offer additional clinical benefits to patients with ST-segment elevation myocardial infarction (STEMI). The Platelet-to-White Blood Cell Ratio (PWR) has been recognized as a prognostic indicator in various diseases. We aimed to explore the relationship between PWR and SR in patients with STEMI undergoing PPCI.

Background: Menisci, one of the most important anatomical structures of the knee joint, plays a role in load transfer, stability, shock absorption, prevention of articular cartilage degeneration, and proprioception. Type I collagen, the main component of the meniscus, and type II collagen fibers play an important role in the stability of the knee joint. This study aimed to evaluate the effects of Naturagen® 4 Joint product containing type I, II, and III collagen on pain, quality of life, and physical functions in patients with meniscopathy.

Corticospinal motor neurons (CSMN), located in the motor cortex of the brain, are one of the key components of the motor neuron circuitry. They are in part responsible for the initiation and modulation of voluntary movement, and their degeneration is the hallmark for numerous diseases, such as amyotrophic lateral sclerosis (ALS), hereditary spastic paraplegia, and primary lateral sclerosis. Cortical hyperexcitation followed by in-excitability suggests the early involvement of cortical dysfunction in ALS pathology.

Article Synopsis
  • AgSbTe is a promising p-type thermoelectric material that has seen improvements focused on reducing lattice thermal conductivity, but its low power factor limits device performance.
  • Recent research shows that doping AgSbTe with Sn creates a new impurity band, enhancing electrical properties and achieving a record-high power factor of 27 μWcmK and a peak thermoelectric figure of merit zT of 2.5 at 673 K.
  • The improved performance is due to increased hole concentration and reduced bipolar conductivity, resulting in an efficient thermoelectric device with energy conversion efficiencies of 12.1% and a power density of 1.13 Wcm.

Revealing the status of forests is important for sustainable forest management. The basis of the concept lies in meeting the needs of future generations and today's generations in the management of forests. The use of remote-sensing (RS) technologies and geographic information systems (GIS) techniques in revealing the current forest structure and in long-term planning of forest areas with multipurpose planning techniques is increasing day by day.

Article Synopsis
  • The study investigates the high prevalence of pain in Parkinson's disease (PD) patients, with 80.6% reporting pain, indicating its significant impact on quality of life.
  • It distinguishes between neuropathic pain (NP) and musculoskeletal pain, finding that longer disease duration predicts NP and that females experience more musculoskeletal pain.
  • The research highlights the correlation between anxiety and central parkinsonian pain and suggests further exploration of amantadine's potential benefits in managing pain, emphasizing the need for personalized treatment approaches in PD.

The aim of the study was to examine the relationship between frailty level and quality of life in elderly individuals with Type 2 diabetes. This descriptive and correlational study was conducted with 211 patients who applied to the diabetes outpatient clinic of a private and a public hospital in Istanbul between September and November 2022. The data were obtained by using the Personal Information Form, Edmonton Frail Scale and the Quality of Life in the Elderly Scale.

Alzheimer's disease (AD) is a neurodegenerative disorder that is characterized by the accumulation of amyloid plaques, phosphorylated tau tangles and microglia toxicity, resulting in neuronal death and cognitive decline. Since microglia are recognized as one of the key players in the disease, it is crucial to understand how microglia operate in disease conditions and incorporate them into models. The studies on human microglia functions are thought to reflect the post-symptomatic stage of the disease.

Lead Sulfide (PbS) has garnered attention as a promising thermoelectric (TE) material due to its natural abundance and cost-effectiveness. However, its practical application is hindered by inherently high lattice thermal conductivity and low electrical conductivity. In this study, we address these challenges by surface functionalization of PbS nanocrystals using CuS molecular complexes-based ligand displacement.

The present study investigated the impact of boric acid (BA) and borax (BX) on markers of inflammation and modifications in miR‑21/PTEN/AKT pathway genes in the liver and kidney tissues of Sprague Dawley male rats with sepsis induced by cecal ligation and puncture (CLP). A total of 60 male Sprague Dawley rats were randomly divided into 6 groups, each containing 10 animals as follows: Control, CLP (where the model was created), 20 mg/kg BX (CLP + BX1), 40 mg/kg BX (CLP + BX2), 20 mg/kg BA (CLP + BA1) and 40 mg/kg BA (CLP + BA2). Liver and kidney tissues were analyzed for histopathological changes, immunopositivity for tumor necrosis factor‑α, interleukin (IL)‑6 and IL‑10, and gene expression of microRNA‑21 (miR‑21), phosphatase and tensin homolog (PTEN) and AKT.

Background: Round shoulder posture (RSP), characterized by forward shoulder positioning from weakened and tense muscles, disrupts normal biomechanics and can cause Subacromial impingement syndrome (SIS), resulting in pain during specific movements or positions. This study examines the immediate effects of Kinesio taping (KT) on pain, proprioception, and posture in individuals in round shoulder individuals with SIS.

Methods: The study involved 114 patients diagnosed with RSP and SIS.

  • - Type 2 diabetes mellitus (DM) is linked to increased risks of sarcopenia (muscle loss) and has a complex relationship with osteoporosis (OP) in postmenopausal women, highlighting the need for further study on these connections.
  • - A study involving 444 postmenopausal women found that those with DM had higher rates of sarcopenia (23.4%) and lower rates of OP (33.5%) compared to controls, suggesting differing impacts of DM on muscle and bone health.
  • - Results indicated that longer menopause duration positively influenced OP risk, while higher age and body mass index correlated with greater sarcopenia risk; DM appeared to negatively impact OLST scores, reflecting challenges

Purpose: Pregnancy induces significant metabolic, immunological, and endocrinological changes to support fetal growth. The 75-gram oral glucose tolerance test (OGTT) is standard for gestational diabetes screening, but concerns exist about its potential to induce oxidative stress, affecting both maternal and fetal health. The aim of the study is examining changes in oxidative stress markers and thiol/disulfide homeostasis in pregnant women to evaluate these concerns.

Article Synopsis
  • * A comparison was made between 195 patients regarding hearing improvement and 211 patients for GSR, focusing on 103 DLG and 108 SLG patients' postoperative results.
  • * Findings revealed that while the DLG group had slightly better hearing averages, there was no significant difference in hearing gain or GSR between DLG and SLG, suggesting DLG may not be the better choice and could potentially negatively impact hearing.

Background: Deep-lobe tumors have been shown to possess a significantly thicker capsule with less tumor penetration compared to superficial tumors. Thus, more conservative surgical approaches, rather than aggressive methods, have been proposed for treating benign deep-lobe tumors of the parotid gland.

Aim: To evaluate the surgical outcomes and oncological safety of selective deep-lobe parotidectomy (SDLP) in patients with benign lesions located in the deep lobe of the parotid gland.
