    Cancer of the esophagus is the eighth most common cancer by incidence worldwide and ranks sixth as the most common cause of cancer death. It is unique among the gastrointestinal tract malignancies because it embodies two distinct histopatologic types, squamous cell carcinoma and adenocarcinoma. Which type of cancer occurs in a given patient or predominates in a given geographic area depends on many variables, including individual lifestyle, socioeconomic pressures, environmental factors and diet and nutrition. Generally for both squamous cell carcinoma and adenocarcinoma of the esophagus case-control studies provide evidence of a protective effect of fruits and vegetables. Here we review the role of nutrition in the etiology of esophageal cancer

    Introduction Fluorescence lifetime imaging ophthalmoscopy (FLIO, Heidelberg Engineering, Figures 1 and 2), a novel in vivo retinal imaging biomarker, generates fluorescence decay lifetimes in 2 spectral channels corresponding to mitochondrial metabolic processes Short Spectral Channel (SSC): 498 – 560 nm Ø Corresponds to flavin adenine dinucleotide (FAD) and oxidative phosphorylation. Long Spectral Channel (LSC): 560 – 720nm Ø Corresponds to predominantly lipofuscin and lysosomal function Based upon animal experimental models and clinical data, mitochondrial dysfunction has a role in the pathophysiology of NMOS

    Background and Objectives: Dry eye disease (DED) affects 5–50% of the global population and deeply influences everyday life activities. This study compared the efficacy, tolerability, and safety of novel Respilac artificial tears containing lipidure and hypromellose (HPMC) with the widely used Nextal artificial tears, which are also HPMC-based, for the treatment of moderate DED in contact lenses (CL) wearers. Materials and Methods: In a prospective, single-center, randomized investigation, 30 patients aged ≥18 years, diagnosed with moderate DED, and wearing CL were randomly assigned to the Respilac (n = 15) or Nextal group (n = 15). Patients self-administrated one drop of Respilac or Nextal in both eyes three times daily for 21 days. Changes in the endpoint (visual analogue scale (VAS) score for ocular tolerability, symptom assessment in dry eye (SANDE) score, non-invasive first break-up time (NIF-BUT) results, tear analysis value, meibography results, and CL tolerability results were assessed, comparing treatment groups and time-point evaluations. Adverse events (AEs) were also recorded and evaluated. Results: VAS scores decreased with time (p \u3c 0.001) in both groups, showing no statistically significant difference among them (p = 0.13). Improvements were also detected from screening to end-of-treatment, which were indicated by the SANDE scores for severity and frequency (p \u3c 0.001) and by tear analysis results (p \u3c 0.001) with no observed difference between the Nextal and Respilac arms. NIF-BUT, meibography, and CL tolerability values were shown to be non-significantly affected by treatment and time. There were no AEs detected in this study cohort. Conclusions: Respilac was confirmed to be effective, safe, and well-tolerated. Lipidure-based ophthalmic solution was shown not to be inferior to the currently used Nextal, however, showing improvements in DED symptoms. Within the existing literature, our study is one of the first to report that MPC plus HPMC-containing eye drops are an effective option for the treatment of moderate dry eye disease and desiccation damage prevention in contact lens wearers

    BACKGROUND: Genome-wide association studies conducted on QRS duration, an electrocardiographic measurement associated with heart failure and sudden cardiac death, have led to novel biological insights into cardiac function. However, the variants identified fall predominantly in non-coding regions and their underlying mechanisms remain unclear. RESULTS: Here, we identify putative functional coding variation associated with changes in the QRS interval duration by combining Illumina HumanExome BeadChip genotype data from 77,898 participants of European ancestry and 7695 of African descent in our discovery cohort, followed by replication in 111,874 individuals of European ancestry from the UK Biobank and deCODE cohorts. We identify ten novel loci, seven within coding regions, including ADAMTS6, significantly associated with QRS duration in gene-based analyses. ADAMTS6 encodes a secreted metalloprotease of currently unknown function. In vitro validation analysis shows that the QRS-associated variants lead to impaired ADAMTS6 secretion and loss-of function analysis in mice demonstrates a previously unappreciated role for ADAMTS6 in connexin 43 gap junction expression, which is essential for myocardial conduction. CONCLUSIONS: Our approach identifies novel coding and non-coding variants underlying ventricular depolarization and provides a possible mechanism for the ADAMTS6-associated conduction changes.BH

    Genome-wide analysis identifies 12 loci influencing human reproductive behavior.

    The genetic architecture of human reproductive behavior-age at first birth (AFB) and number of children ever born (NEB)-has a strong relationship with fitness, human development, infertility and risk of neuropsychiatric disorders. However, very few genetic loci have been identified, and the underlying mechanisms of AFB and NEB are poorly understood. We report a large genome-wide association study of both sexes including 251,151 individuals for AFB and 343,072 individuals for NEB. We identified 12 independent loci that are significantly associated with AFB and/or NEB in a SNP-based genome-wide association study and 4 additional loci associated in a gene-based effort. These loci harbor genes that are likely to have a role, either directly or by affecting non-local gene expression, in human reproduction and infertility, thereby increasing understanding of these complex traits

    INFRARED TUNABLE DIODE LASER SECOND DERIVATIVE MODULATION SPECTROSCOPY HAS BEEN USED TO MONITOR TRACE GASES IN THE TROPOSPHERE: IN THE CASE OF UNSTABLE OR REACTIVE GASES HOWEVER, CALIBRATION OF THE MEASUREMENT IS A DIFFICULT TASK. IN SOME CASES, THE ABSORPTION DUE TO ATMOSPHERIC CARBON DIOXIDE OR NITROUS OXIDE SIMULTANEOUSLY RECORDED WITH THE TRACE GAS ABSORPTION APPEARS USABLE AS A BUILT-IN CALIBRATION STANDARD: THE PROCEDURE IS DISCUSSED AND EXAMPLES OF POTENTIAL APPLICATIONS ARE GIVEN.NA-NOT AVAILABL
