Curative resection of leiomyosarcoma of the descending colon with metachronous liver metastasis: A case report.

Background: Leiomyosarcoma (LMS) has a poor prognosis and rarely originates from the colon. If resection is possible, surgery is the first treatment most commonly considered. Unfortunately, no standard treatment exists for hepatic metastasis of LMS; although, several treatments, such as chemotherapy, radiotherapy, and surgery, have been used.

Impacts of the COVID-19 crisis on single-person households in South Korea.

Using nationally representative income and expenditure data from South Korea, we show that single-person households suffered a much greater decrease in household income and expenditure compared to multi-persons households during the COVID-19 pandemic in 2020. Negative effects on income were largest for the single-person households in ages 50-64, mostly driven by decreases in earned income rather than business income. There was no corresponding decrease in consumption expenditures, however, other than on transportation expenditure for young men.

Physico-mechanical and in-vivo evaluations of tri-layered alginate-gelatin/polycaprolactone-gelatin-β-TCP membranes for guided bone regeneration.

Guided bone regeneration (GBR) membranes favor periodontal regrowth, but they still have certain limitations, such as improper biodegradation and poor mechanical property. To overcome these shortcomings, we have generated a unique multifunctional membrane. A polycaprolactone/gelatin/β-TCP and alginate/gelatin trilayered construction was fabricated through electrospinning and casting technology.

Gender gaps in cognitive and social-emotional skills in early primary grades: Evidence from rural Indonesia.

This paper examines the magnitude and source of gender gaps in cognitive and social-emotional skills in early primary grades in rural Indonesia. Relative to boys, girls score more than 0.17 SD higher in tests of language and mathematics (cognitive skills) and between 0.

Does college education make people politically liberal?: Evidence from a natural experiment in South Korea.

Our study examines the impact of college education on individuals' ideological orientations (identifying as politically liberal or conservative) using a massive expansion of opportunities to attend college known as the graduation quota program in South Korea. A 1979 military coup in South Korea mandated that all public and private colleges expand their college admission quotas by thirty percent in 1981 and fifty percent in 1982. As an ideal natural experiment for our study, the mandatory increases in college enrollment happened quickly and exogenously in a short timeframe.

In vitro and in vivo evaluation of effectiveness of a novel TEMPO-oxidized cellulose nanofiber-silk fibroin scaffold in wound healing.

In this study, a novel TEMPO-oxidized cellulose nanofiber (TOCN)-silk fibroin scaffold was prepared using a cost effective freeze drying method. Fundamental physical characterizations were carried out by scanning electron microscopy (SEM), pore diameter determination, FT-IR. PBS uptake behavior of the scaffold showed that, silk fibroin can enhance the swelling capacity of TOCN.

Examination of In vitro and In vivo biocompatibility of alginate-hyaluronic acid microbeads As a promising method in cell delivery for kidney regeneration.

In this study, alginate (ALG) and alginate-hyaluronic acid (ALG-HA) injectable microbeads, with the purpose of delivering stem cells for tissue engineering, were prepared by a spraying method into a CaCl solution that shows high porosity for the exchange of nutrition and waste. In addition, the size distribution and surface morphology was investigated using optical and scanning electron microscopy, respectively. The chemical structural properties of the ALG-HA microbeads were examined by Fourier transform infrared spectroscopy.

Is obesity related to deteriorating mental health of the U.S. working-age population?

This study examined whether the association between obesity and non-specific mental distress has become stronger among the working-age population over time and whether a change in the association was moderated by particular socioeconomic characteristics. More than two million adults aged 20-55, from 1993 to 2010 (except for 2002), were analyzed using self-reported Mentally Unhealthy Days (a measure of non-specific mental distress) and Body Mass Index (BMI) from the Behavioral Risk Factor Surveillance System annual survey. This study found that prevalence of obesity more than doubled (p < 0.

The BRAF mutation is associated with the prognosis in colorectal cancer.

Background: Two members of the Ras/Raf signaling pathway, KRAS and B-raf, are suspected to be involved in the stepwise progression of colorectal cancer (CRC) tumorigenesis.

Objective: We compared the KRAS and BRAF mutation status of CRC patients with their clinicopathological characteristics and examined the effect of mutation status on survival rates.

Methods: DNA was extracted from 164 samples, and the mutation statuses of KRAS and BRAF were assessed using peptide PNA clamp real-time PCR method.
