Characterizing the Impacts of 2024 Total Solar Eclipse Using New York State Mesonet Data.

On 8 April 2024, a rare total solar eclipse (TSE) passed over western New York State (NYS), the first since 1925 and the last one until 2079. The NYS Mesonet (NYSM) consisting of 126 weather stations with 55 on the totality path provides unprecedented surface, profile, and flux data and camera images during the TSE. Here we use NYSM observations to characterize the TSE's impacts at the surface, in the planetary boundary layer (PBL), and on surface fluxes and CO concentrations.

Actívatexto: Feasibility and Acceptability of a Mobile Intervention That Promotes Smoking Cessation and Physical Activity among Latinos.

Unlabelled: The purpose of this study was to assess the feasibility and acceptability of a mobile intervention that promotes smoking cessation and physical activity among Latinos living in the United States. Twenty Latino adults who smoked and did not meet recommended levels of physical activity were recruited using community-based recruitment strategies. Participants received Actívatexto, a theory-based, culturally accommodated, 12-week text messaging intervention (available in English and Spanish) that promotes smoking cessation and physical activity.

Outer surface protein E (OspE) mediates Borrelia burgdorferi sensu stricto strain-specific complement evasion in the eastern fence lizard, Sceloporus undulatus.

In North America, Lyme disease is primarily caused by the spirochetal bacterium Borrelia burgdorferi sensu stricto (Bb), which is transmitted between multiple vertebrate hosts and ixodid ticks, and is a model commonly used to study host-pathogen interactions. While Bb is consistently observed in its mammalian and avian reservoirs, the bacterium is rarely isolated from North American reptiles. Two closely related lizard species, the eastern fence lizard (Sceloporus undulatus) and the western fence lizard (Sceloporus occidentalis), are examples of reptiles parasitized by Ixodes ticks.

Iron-binding cellular profile of transferrin using label-free Raman hyperspectral imaging and singular value decomposition (SVD).

Serum transferrin (Tf) is the essential iron transport protein in the body. Transferrin is responsible for the sequestration of free iron in serum and the delivery of iron throughout the body and into cells, where iron is released inside a mildly acidified endosome. Altered iron distributions are associated with diseases such as iron-overload, cancer, and cardiovascular disease.

Dual wavelength digital holographic imaging of layered structures.

We present a dual wavelength digital holographic technique for three-dimensional microscopic imaging of layered structures, where layers are separated from one another by the axial distances exceeding the wavelength of imaging light. Our methodology not only provides the three-dimensional structure of each layer, but also allows the height differentiation of distinct layers. We have also implemented a technique suppressing low intensity signal when no reliable phase information can be extracted, based on the quality of the interference fringe pattern.

Quantitative label-free imaging of iron-bound transferrin in breast cancer cells and tumors.

Transferrin (Tf) is an essential serum protein which delivers iron throughout the body via transferrin-receptor (TfR)-mediated uptake and iron release in early endosomes. Currently, there is no robust method to assay the population of iron-bound Tf in intact cells and tissues. Raman hyperspectral imaging detected spectral peaks that correlated with iron-bound Tf in intact cells and tumor xenografts sections (~1270-1300 cm).

Raman Spectroscopy Allows for the Determination of Elephant Ivory Age.

Determination of the age of ivory is important for controlling illegal trafficking and the proper identification of ivory artifacts. Radiocarbon dating is the standard method of determining the age of ivories; however, it requires the destruction of a fragment of the sample. Raman spectroscopy is a nondestructive technique, and therefore can be used on artwork.

Characterization of nanofibers for tissue engineering: Chemical mapping by Confocal Raman microscopy.

Nanofiber scaffolds are used in bioengineering for functional support of growing tissues. To fine tune nanofiber properties for specific applications, it is often necessary to characterize the spatial distribution of their chemical content. Raman spectroscopy is a common tool used to characterize chemical composition of various materials, including nanofibers.

Reproductive decisions as mediators between education and employment of women in Kyrgyzstan.

Researchers created a large body of evidence showing that education and fertility are strong determinants of women's employment. In postsocialist economies, women's reproductive decisions have become more critical to employment opportunities. Yet the issue is not well-understood.

A Woman'S Status and Prenatal Care Utilization in Patrilocal Households of Post-Soviet Countries.

Women's household autonomy is associated with maternal healthcare utilization in developing countries, but its effects are not consistently positive. In the current study, the researchers test prenatal care utilization in Armenia and Azerbaijan (N = 2,159). After controlling for socioeconomic factors, we find that women's autonomy seems to be a mixed blessing.

Methamphetamine Induces Apoptosis of Microglia via the Intrinsic Mitochondrial-Dependent Pathway.

Methamphetamine (METH) is a drug of abuse, the acute and chronic use of which induces neurotoxic responses in the human brain, ultimately leading to neurocognitive disorders. Our goals were to understand the impact of METH on microglial mitochondrial respiration and to determine whether METH induces the activation of the mitochondrial-dependent intrinsic apoptosis pathway in microglia. We assessed the expression of pro- apoptosis genes using qPCR of RNA extracted from a human microglial cell line (HTHU).

Correlates of HIV and Inconsistent Condom Use Among Female Sex Workers in Ukraine.

While female sex workers (FSWs) carry one of the highest risks of HIV transmission, little is known about predictors of HIV and risky behavior of FSWs in Ukraine. In this study of 4806 Ukrainian FSWs, the prevalence of HIV was 5.6 %.

Problematic drinking and physiological responses among female college students.

Problematic drinking is a widespread problem among college students, and can contribute to alcohol dependence during later adulthood, particularly among females. The current study assessed vulnerability for alcohol-related consequences by comparing self-reported drinking with coping styles and physiological and behavioral stress responses during a challenging task. Cardiovascular measurements and saliva samples were taken from 88 female students at the beginning of the experiment and after the task.

Randomized clinical trials and observational studies: guidelines for assessing respective strengths and limitations.

The 2 primary types of studies that are used to test new drugs or procedures or compare competing drugs or types of procedures are randomized clinical trials (RCTs) and observational studies (OS). Although it would appear that RCTs always trump OS because they eliminate selection bias, there are many possible limitations to both types of studies, and these limitations must be carefully assessed when comparing the results of RCTs and OS. This state-of-the art review describes these limitations and discusses how to assess the validity of RCTs and OS that yield different conclusions regarding the relative merit of competing treatments/interventions.
