Introduction: Distal junctional kyphosis (DJK) and distal junctional failure (DJF) are known complications of adult multilevel spinal fusion surgery. Previous literature has extensively investigated proximal junctional kyphosis (PJK) and proximal junctional failure (PJF), but DJK and DJF are relatively under-studied. This study investigates the association between bone mineral density (BMD) and DJK/DJF via a Systematic Review (SR) and Meta-Analysis (MA).

Objectives: To provide a qualitative and quantitative evaluation by demonstrating measurements of the proximity of vital structures involved and assessed injuries during a T12-corpectomy and cage implantation via a far lateral approach.
Material And Methods: Six fresh-frozen adult cadaveric specimens were dissected according to standardized protocol.
Aims And Objectives: To assess the serum cortisol level in patients with oral squamous cell carcinoma and correlate this value with clinical staging of tumor using TNM staging, histopathological grading of the tumor using BRYNE'S (1992) invasive tumor front grading system and nodal metastasis using histopathology.
Materials And Methods: In this prospective study a total of 25 patients who reported with biopsy proven oral squamous cell carcinoma from Dec 2012-Nov 2014 were included. Patient's clinical parameters were recorded.
Microtubules are dynamic polymers composed of α- and β-tubulin heterodimers. Microtubules are universally conserved among eukaryotes and participate in nearly every cellular process, including intracellular trafficking, replication, polarity, cytoskeletal shape, and motility. Due to their fundamental role in mitosis, they represent a classic target of anti-cancer therapy.

Given the dosimetric advantages of proton therapy, we aimed to assess oncologic and toxicity outcomes of patients with re-RT to the pelvis/abdomen with intensity modulated proton therapy (IMPT) for gynecologic cancers.
Methods And Materials: We performed a retrospective analysis of all patients with gynecologic cancer treated at a single institution between 2015 and 2021 with IMPT re-RT.
Treatments for advanced and recurrent ovarian cancer remain a challenge due to a lack of potent, selective, and effective therapeutics. Here, we developed the basis for a transformative anticancer strategy based on anthrax toxin that has been engineered to be selectively activated by the catalytic power of zymogen-activating proteases on the surface of malignant tumor cells to induce cell death. Exposure to the engineered toxin is cytotoxic to ovarian tumor cell lines and ovarian tumor spheroids derived from patient ascites.

Microtentacles (McTNs) are tubulin-based projections observed in detached breast cancer cells. In this study, we investigated whether ovarian cancers exhibit McTNs and characterized McTN biology.

Additional objectives were to examine the role of prior bevacizumab and taxanes, and explore class III-ß-tubulin (TUBB3) as a predictive biomarker.
Methods: Participants were randomised to receive ixabepilone 20 mg/m days 1, 8, 15 with (IXA + BEV) or without (IXA) bevacizumab 10 mg/kg days 1, 15 every 28 days.
The urban poor in developing countries face challenging living environments, which may interfere with good sleep. Using actigraphy to measure sleep objectively, we find that low-income adults in Chennai, India, sleep only 5.5 hours a night on average despite spending 8 hours in bed.

Histologically, it is characterized by sheets and islands of vacuolated/clear cells. Till date, only 74 cases have been reported in the literature.

This carries significant morbidity and can be technically difficult. An alternative is stand-alone lateral lumbar interbody fusion (LLIF), which may avoid complications associated with revision surgery.

We review the interdisciplinary evidence of the bidirectional causal relationship between poverty and common mental illnesses-depression and anxiety-and the underlying mechanisms. Research shows that mental illness reduces employment and therefore income, and that psychological interventions generate economic gains. Similarly, negative economic shocks cause mental illness, and antipoverty programs such as cash transfers improve mental health.

An emerging role has been shown for eicosanoids in the pathogenesis of gynecological malignancies which include cancers of the vulva, vagina, cervix, uterine, and ovary. Eicosanoid biosynthesis pathways start at the metabolism of phospholipids by phospholipase A2 then proceeding to one of three pathways: the cyclooxygenase (COX), lipoxygenase (LOX), or P450 epoxygenase pathways.

Design: A total of 1381 patients with nonsyndromic cleft lip and palate were included in the study. This is a hospital-based retro-prospective case record analysis.
Introduction: Implant subsidence is a potential complication of spinal interbody fusion and may negatively affect patients subjected to procedures relying on indirect decompression such as minimally invasive transpsoas lateral lumbar interbody fusion (LLIF). The porous architecture of a recently developed titanium intervertebral cage maximizes bone-to-implant contact and minimizes stress shielding in laboratory experiments; however, its subsidence rate in patients has not yet been evaluated. The goal of this current study was to evaluate implant subsidence in patients subjected to LLIF.

We have previously observed that SIRT1 co-localizes with surviving OLGs in multiple sclerosis (MS) plaques, but it is not yet known whether SIRT1 is involved in OLGs survival after exposure to sublytic C5b-9. We have now investigated the role of SIRT1 in OLGs differentiation and the effect of sublytic levels of C5b-9 on SIRT1 and phosphorylated-SIRT1 (Ser27) expression.

Upregulation of class III β-tubulin has previously been shown to confer taxane resistance in a variety of human cancers. Prostaglandin E receptor EP4 is linked to progression of a variety of human cancers and may represent a novel target for tumor inhibition in LMS.

However, a decision-making algorithm for selective use of the zygomatic osteotomy and the impact of the zygomatic osteotomy on surgical complications have not been well documented. We described an algorithm for deciding whether to use a zygomatic osteotomy in MCF surgery and evaluated complications associated with a zygomatic osteotomy.
