Bisphosphonates and Their Connection to Dental Procedures: Exploring Bisphosphonate-Related Osteonecrosis of the Jaws.

Bisphosphonates are widely used to treat osteoporosis and malignant tumors due to their effectiveness in increasing bone density and inhibiting bone resorption. However, their association with bisphosphonate-related osteonecrosis of the jaws (BRONJ) following invasive dental procedures poses a significant challenge. This review explores the functions, mechanisms, and side effects of bisphosphonates, emphasizing their impact on dental procedures.

Unraveling the interplay between norovirus infection, gut microbiota, and novel antiviral approaches: a comprehensive review.

Norovirus infection is a leading cause of acute gastroenteritis worldwide and can also cause harmful chronic infections in individuals with weakened immune systems. The role of the gut microbiota in the interactions between the host and noroviruses has been extensively studied. While most past studies were conducted or focused on murine noroviruses, recent research has expanded to human noroviruses using or human intestinal enteroids culture studies.

Novel cancer treatment paradigm targeting hypoxia-induced factor in conjunction with current therapies to overcome resistance.

Chemotherapy, radiotherapy, targeted therapy, and immunotherapy are established cancer treatment modalities that are widely used due to their demonstrated efficacy against tumors and favorable safety profiles or tolerability. Nevertheless, treatment resistance continues to be one of the most pressing unsolved conundrums in cancer treatment. Hypoxia-inducible factors (HIFs) are a family of transcription factors that regulate cellular responses to hypoxia by activating genes involved in various adaptations, including erythropoiesis, glucose metabolism, angiogenesis, cell proliferation, and apoptosis.

Comparison of the Efficacy of Single-Injection Regional Analgesia Techniques for Total Abdominal Hysterectomy: A Systematic Review and Network Meta-Analysis.

Background: Single-injection regional analgesia techniques can provide effective analgesia for abdominal hysterectomy. However, few randomized controlled trials (RCTs) have directly compared these techniques for total abdominal hysterectomy (TAH), and the best strategy remains unknown.

Objectives: In this network meta-analysis, we compared the analgesic efficacy of single-injection regional analgesia techniques in patients who underwent TAH.

DHA-containing phospholipids control membrane fusion and transcellular tunnel dynamics.

Metabolic studies and animal knockout models point to the critical role of polyunsaturated docosahexaenoic acid (22:6, DHA)-containing phospholipids (DHA-PLs) in physiology. Here, we investigated the impact of DHA-PLs on the dynamics of transendothelial cell macroapertures (TEMs) triggered by RhoA inhibition-associated cell spreading. Lipidomic analyses showed that human umbilical vein endothelial cells (HUVECs) subjected to a DHA diet undergo a 6-fold enrichment in DHA-PLs at the plasma membrane (PM) at the expense of monounsaturated oleic acid-containing PLs (OA-PLs).

Adult False Vocal Cord Cavernous Lymphangioma Presenting with Hemoptysis: A Case Report.

Lymphangiomas are rare benign tumors of the lymphatic system, most often found at birth and before the age of 2 years. The head and neck region are the most frequent locations for lymphangioma. Involvement of the adult larynx in isolation is rare, and only a few cases have been reported so far.

Effects of branched-chain amino acid-rich supplementation on EWGSOP2 criteria for sarcopenia in older adults: a systematic review and meta-analysis.

Purpose: According to criteria recommended by the European Working Group on Sarcopenia in Older People 2 (EWGSOP2), we analyzed the effects of branched-chain amino acid (BCAA)-rich supplements on muscle strength, muscle mass, and physical performance in older people.

Methods: We searched PubMed, Embase, Cochrane Library, and CINAHL from inception until March 2021. Randomized controlled trials that examined the effect of BCAA-rich supplements on older people were included.

The impact of biomechanics on corneal endothelium tissue engineering.

The integrity of innermost layer of the cornea, the corneal endothelium, is key to sustaining corneal transparency. Therefore, disease or injury causing loss or damage to the corneal endothelial cell population may threaten vision. Transplantation of corneal tissue is the standard treatment used to replace malfunctioning corneal endothelial cells.

Molecular and cellular dissection of the oxysterol-binding protein cycle through a fluorescent inhibitor.

ORPphilins are bioactive natural products that strongly and selectively inhibit the growth of some cancer cell lines and are proposed to target intracellular lipid-transfer proteins of the oxysterol-binding protein (OSBP) family. These conserved proteins exchange key lipids, such as cholesterol and phosphatidylinositol 4-phosphate (PI(4)P), between organelle membranes. Among ORPphilins, molecules of the schweinfurthin family interfere with intracellular lipid distribution and metabolism, but their functioning at the molecular level is poorly understood.

A case of palatine tonsillar metastasis of lung adenocarcinoma: A CARE-compliant article.

Rationale: Palatine tonsil is an extremely rare site for metastatic disease, accounting for 0.8% of malignant tonsillar neoplasms. To the best of our knowledge, this is the first report of metastatic adenocarcinoma in the tonsil treated with wide excision and targeted therapy, with no local recurrence 6 months postoperatively.

ADP-ribosylation factor-like 4A interacts with Robo1 to promote cell migration by regulating Cdc42 activation.

Cell migration is a highly regulated event that is initiated by cell membrane protrusion and actin reorganization. Robo1, a single-pass transmembrane receptor, is crucial for neuronal guidance and cell migration. ADP-ribosylation factor (Arf)-like 4A (Arl4A), an Arf small GTPase, functions in cell morphology, cell migration, and actin cytoskeleton remodeling; however, the molecular mechanisms of Arl4A in cell migration are unclear.

Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner.

One challenge in cell biology is to decipher the biophysical mechanisms governing protein enrichment on curved membranes and the resulting membrane deformation. The ERM protein ezrin is abundant and associated with cellular membranes that are flat, positively or negatively curved. Using and cell biology approaches, we assess mechanisms of ezrin's enrichment on curved membranes.

Effusion-based lymphoma with morphological regression but with clonal genetic features after aspiration.

Effusion-based lymphoma (EBL) is a rare but distinct entity of large B-cell lymphoma in effusion without association with human herpes virus-8 (HHV-8). Spontaneous regression after pleurocentesis has been observed; but to our knowledge, there are no reports on the morphological and molecular features of subsequent aspirations in regressing cases. Here, we report the case of a 92-year-old male with chronic obstructive pulmonary disease, who presented with right pleural effusion.

Fatal spontaneous rupture of common iliac artery associated with fibromuscular dysplasia.

A previously healthy 25-year-old man with no known risk factors was presented at the emergency room with a 3 h history of abdominal and loin pain. Physical examination and lab data showed no specific findings except tenderness, slight white cell count elevation and decreased haemoglobin level. The patient's condition deteriorated over the following hours and he died despite resuscitation attempts.

DDR2 overexpression in urothelial carcinoma indicates an unfavorable prognosis: a large cohort study.

The migration ability of urothelial carcinoma corresponding to dismal prognosis had not been fully investigated. The interaction of extracellular collagen with a unique transmembrane receptor tyrosine kinase, Discoidin domain receptor 2 (DDR2), was selected by data mining. We arranged real-time reverse transcription polymerase chain reaction assays to evaluate the transcript levels in 26 urinary tract urothelial carcinoma and 26 urinary bladder urothelial carcinoma specimens, showing significantly increase corresponding to advanced primary stage (p = 0.

Efficiency Enhancement of Nanotextured Black Silicon Solar Cells Using Al2O3/TiO2 Dual-Layer Passivation Stack Prepared by Atomic Layer Deposition.

In this study, efficient nanotextured black silicon (NBSi) solar cells composed of silicon nanowire arrays and an Al2O3/TiO2 dual-layer passivation stack on the n(+) emitter were fabricated. The highly conformal Al2O3 and TiO2 surface passivation layers were deposited on the high-aspect-ratio surface of the NBSi wafers using atomic layer deposition. Instead of the single Al2O3 passivation layer with a negative oxide charge density, the Al2O3/TiO2 dual-layer passivation stack treated with forming gas annealing provides a high positive oxide charge density and a low interfacial state density, which are essential for the effective field-effect and chemical passivation of the n(+) emitter.
