Extensive global research conducted over 30 years explores asphalt leachability and stormwater runoff. Asphalt's widespread usage in construction materials underscores the importance of understanding its environmental consequences. This study aims to assess the influence of sunlight exposure on water quality, particularly regarding the release of hazardous organic compounds such as polycyclic aromatic compounds.

Intraoperative Methadone Reduces Postoperative Opioid Requirements in Nuss Procedure for Pectus Excavatum.

Introduction: Surgical correction of pectus excavatum by Nuss procedure, commonly referred to as minimally invasive repair of pectus excavatum (MIRPE), often results in significant postoperative pain. This study investigated whether adding intraoperative methadone would reduce the postoperative opioid requirement during admission for patients undergoing MIRPE.

Methods: A retrospective cohort chart review was conducted for 40 MIRPE patients between 2018 and 2020.

Helicase-like transcription factor-deletion from the tumor microenvironment in a cell line-derived xenograft model of colorectal cancer reprogrammed the human transcriptome-S-nitroso-proteome to promote inflammation and redirect metastasis.

Methylation of the HLTF gene in colorectal cancer (CRC) cells occurs more frequently in men than women. Progressive epigenetic silencing of HLTF in tumor cells is accompanied by negligible expression in the tumor microenvironment (TME). Cell line-derived xenografts (CDX) were established in control (Hltf+/+) and Hltf-deleted male Rag2-/-IL2rg-/- mice by direct orthotopic cell microinjection (OCMI) of HLTF+/+HCT116 Red-FLuc cells into the submucosa of the cecum.

Quantitative measurements of prostate capsule and gland density and their correlation to prostate size: possible clinical implications in prostate cancer.

Purpose: To study histo-anatomical imaging features and possible association between prostate volume, capsule thickness and glandular density within the peripheral zone (PZ) of prostates of different sizes.

Methods: Patients were selected who had undergone radical prostatectomy. Specimen selection was based on two factors: first, easy reconstruction of prostate anatomy by the histological slides; and second, based on prostate size.

Helicase-like transcription factor (Hltf) gene-deletion promotes oxidative phosphorylation (OXPHOS) in colorectal tumors of AOM/DSS-treated mice.

The helicase-like transcription factor (HLTF) gene-a tumor suppressor in human colorectal cancer (CRC)-is regulated by alternative splicing and promoter hypermethylation. In this study, we used the AOM/DSS-induced mouse model to show Hltf-deletion caused poor survival concomitant with increased tumor multiplicity, and dramatically shifted the topographic distribution of lesions into the rectum. Differential isoform expression analysis revealed both the truncated isoform that lacks a DNA-repair domain and the full length isoform capable of DNA damage repair are present during adenocarcinoma formation in controls.

Possible clinical implications of peripheral zone changes depending on prostate size.

Purpose: Although numerous studies have observed an inverse relationship between the size of benign prostate hypertrophy (BPH) and the incidence of prostate cancer (PCa), few studies have explored specific mechanisms by which BPH and PCa may influence one another. In a recent study, one possibility has been brought up that growth in the transition zone due to BPH may cause pressure-induced fibrotic changes in the peripheral zone, an area where 80% of cancer occurs, leading to gland atrophy and the thickening of the prostatic capsule. To shed more light on this phenomenon, we conducted a pilot study examining the quantitative and qualitative histo-anatomical changes that occur in the peripheral zone associated with BPH.

Histological changes of the peripheral zone in small and large prostates and possible clinical implications.

Introduction: It is well documented in literature that most prostate carcinomas (PCa) arise in the peripheral zone (PZ). Additionally, an inverse relationship between prostate size and the incidence of PCa has been demonstrated in recent studies. However, little is known about gland distribution in the peripheral zone of larger prostates compared to smaller prostates.

Alternative splicing of helicase-like transcription factor (Hltf): Intron retention-dependent activation of immune tolerance at the feto-maternal interface.

Hltf is regulated by intron retention, and global Hltf-deletion causes perinatal lethality from hypoglycemia. In heart, full-length Hltf is a transcriptional regulator of Hif-1α that controls transport systems. Thus, we tested the hypothesis that Hltf deletion from placenta caused or exacerbated neonatal hypoglycemia via Hif-1α regulation of nutrient transporters.

Development and validation of a Clostridium difficile risk assessment tool.

The incidence of Clostridium difficile infection has increased rapidly during the past decade, increasing lengths of stays in the hospital, costs, and mortality rates. To address this increased incidence, we performed a retrospective case-control study using known risk factors to develop a tool to determine which patients are at risk for infection. Multivariate analysis generated a combination of risk factors associated with development of infection including prior admission, endoscopy within 30 days, cephalosporin/fluoroquinolone use, length of stay 7 days or longer, age 65 years or older, body mass index less than 25, and albumin level less than 2.

Effects of abiraterone acetate on androgen signaling in castrate-resistant prostate cancer in bone.

Purpose: Persistent androgen signaling is implicated in castrate-resistant prostate cancer (CRPC) progression. This study aimed to evaluate androgen signaling in bone marrow-infiltrating cancer and testosterone in blood and bone marrow and to correlate with clinical observations.

Patients And Methods: This was an open-label, observational study of 57 patients with bone-metastatic CRPC who underwent transiliac bone marrow biopsy between October 2007 and March 2010.

Video-assisted transumbilical Meckel's diverticulectomy in children.

The treatment of Meckel's diverticulum (MD) in children is resection. Some data exist for the use of laparoscopic resection. The Video-Assisted Transumbilical (VAT) single-trocar technique has been recently described for appendectomy.

Overexpression of defense response genes in transgenic wheat enhances resistance to Fusarium head blight.

Fusarium head blight (FHB) of wheat, caused by Fusarium graminearum and other Fusarium species, is a major disease problem for wheat production worldwide. To combat this problem, large-scale breeding efforts have been established. Although progress has been made through standard breeding approaches, the level of resistance attained is insufficient to withstand epidemic conditions.

What do consumers and healthcare providers in West Virginia think of long-term care?

In recent years, the media has portrayed long-term care in a negative light, with exposè news stories on skilled nursing facilities, personal care homes, and hospitals that provide long-term care. There have been few positive news stories to counter the negative ones, and there is concern that the public perception of long-term care is inaccurate. The authors conducted the following study to evaluate how the West Virginia consumer perceives and defines long-term care and if there is a difference in that perception as compared with healthcare workers' perceptions and definitions of long-term care.

Video-assisted transumbilical appendectomy in children.

Background: Video-assisted transumbilical appendectomy (VATA) is a combination of laparoscopic and open techniques and is not widely used in children. We are reporting our most recent experience with this technique.

Methods: After the institutional review board approval, the charts of patients who underwent VATA between December 2003 and October 2004 were retrospectively reviewed.

Lipid metabolism and adipokine levels in fatty acid-binding protein null and transgenic mice.

Fatty acid-binding proteins (FABPs) facilitate the diffusion of fatty acids within cellular cytoplasm. Compared with C57Bl/6J mice maintained on a high-fat diet, adipose-FABP (A-FABP) null mice exhibit increased fat mass, decreased lipolysis, increased muscle glucose oxidation, and attenuated insulin resistance, whereas overexpression of epithelial-FABP (E-FABP) in adipose tissue results in decreased fat mass, increased lipolysis, and potentiated insulin resistance. To identify the mechanisms that underlie these processes, real-time PCR analyses indicate that the expression of hormone-sensitive lipase is reduced, while perilipin A is increased in A-FABP/aP2 null mice relative to E-FABP overexpressing mice.

Investigation of in vivo fatty acid metabolism in AFABP/aP2(-/-) mice.

The metabolic impact of the murine adipocyte fatty acid-binding protein (AFABP/aP2) on lipid metabolism was investigated in the AFABP/aP2(-/-) mouse and compared with wild-type C57BL/6J littermates. Mice were weaned on a high-fat diet (59% of energy from fat) and acclimated to meal feeding. Stable isotopes were administered, and indirect calorimetry was performed to quantitate fatty acid flux, dietary fatty acid utilization, and substrate oxidation.
