Latest improvements within microbe capture of hydrogen sulfide via bad gasoline by way of sulfur-oxidizing bacteria.
Four hundred and eighty (PIC 337 X 1050, PIC Genus, Hendersonville, TN) pigs were used to evaluate a novel threonine source (ThrPro, CJ America Bio, Fort Dodge, IA) for nursery pigs from approximately 7 to 20 kg body weight (BW). After weaning, pigs were sorted by sex and fed a common diet for 1 wk. Upon completion of the first week, pigs were sorted into randomized complete blocks, equalized by weight, within 16 replications. check details Pigs were allocated to one of three dietary treatments positive control (POS)-standard ileal digestible threonine-to-lysine ratio (SID; ThrLys) 0.60, negative control (NEG)-SID ThrLys ≤0.46, and alternative Thr source (TEST)-SID ThrLys 0.60. The alternative Thr source included fermentative biomass and was assumed to contain 75% Thr and a digestibility coefficient of 100% based on the manufacturer's specifications. All other nutrients met or exceeded the NRC recommendations. Growth and intake data were analyzed as repeated measures with a compound symmetry covariance structure using the daily feed intake was not significantly different across treatments for the entirety of the study. In conclusion, the replacement of crystalline L-Thr with a novel Thr source resulted in similar growth performance in nursery pigs from approximately 7 to 20 kg.Most tall fescue [Lolium arundinaceum (Schreb.) Darbysh] in the Southeastern United States contains an endophyte that causes fescue toxicosis (FT) in grazing animals, a serious disease that causes approximately $1 billion in economic losses to the animal industries in the United States. Recently, a genetic test called T-Snip (AgBotanica, LCC, Columbia, MO), was developed with the objective of identifying animals with genetic variation for FT tolerance. The aim of this study was to validate the use of this genetic test in mature, pregnant cows. Over 13 wk, weekly phenotypic data, including body weight, rectal temperatures, hair coat scores, hair shedding scores, and body condition scores, were collected on 148 pregnant purebred Angus cows at 2 locations in NC where infected fescue was the primary source of feed. Birth weights (cBW) and 205-d adjusted weaning weights (adjWW) from these cow's calves were recorded. All cows were genotyped for T-Snip. At the end of the trial, each phenotypic trait was calculated a may be predictive of cow performance (aBWd, aBCSd, and adjWW) in an endophyte-infected tall fescue environment.The objective of this study was to evaluate and to estimate the relationship between fecal egg counts (FECs) and FAMACHA score and the body weight of growing Katahdin rams during a parasite challenge. One of the largest factors negatively influencing reproduction and economics in the sheep industry is gastrointestinal nematode (GIN) parasites. Due to anthelmintic resistance of these parasites, animals are selected for parasite resistance using FEC and FAMACHA scores. Data were used from the Virginia Tech Southwest Agricultural Research and Extension Center Ram Test in Glade Spring, VA, from the year 2012 to 2018 in which animals were tested in 14-d intervals for 70 d. Mixed models for repeated weight measurements were made from backward stepwise selection to evaluate the relationships between weight and GIN FEC. A total of 576 animals within 23 contemporary groups derived from test year and pasture group were analyzed. Ram, contemporary group, and consignor were considered random effects, and fixed effects were birth type, test day, age, age squared, starting weight, FEC, and FAMACHA score. Pairwise contrasts were used in the statistical analysis of parameters and their interactions. Weight and age were found to have a quadratic relationship. Increased FEC was associated with weight loss at a rate of 0.00030 kg/FEC (P less then 0.0001). Animals dewormed at any point during the trial weighed less than those that were not and increased with test day to a maximum difference of 4.66 kg (P less then 0.001). FAMACHA score was found to be significant (P less then 0.05), but a direct relationship with weight was not conclusive. Overall, rams with severe enough parasite load to require deworming had lesser weights, which could impact the profitability of sheep production and reinforced the need to select animals that had greater innate parasite resistance.Supplemental Digital Content is available in the text.
To describe telemedicine utilization in neurosurgery at a single tertiary institution to provide outpatient care during the coronavirus disease 2019 (COVID-19) pandemic, with 315 telemedicine visits performed by the neurosurgery department.

In response to the COVID-19 pandemic national stay-at-home orders and postponed elective surgeries, we converted upcoming clinic visits into telemedicine visits and rescheduled other patients thought not to be markedly affected by surgical postponement. We reviewed the charts of all patients who had telehealth visits from April 1 through April 30, 2020, and collected demographic information, diagnosis, type of visit, and whether they received surgery; a satisfaction questionnaire was also administered.

In March 2020, 94% (644 of 685) of the neurosurgery clinic visits were face-to-face, whereas in April 2020, 55% (315 of 573) of the visits were telemedicine (
<.001). In April, of the 315 telemedicine visits, 172 (55%) were phone consults and 143 (45%) video consul tool for preoperative consultation, postoperative and follow-up visits during the COVID-19 pandemic, and decreased risks of exposure to severe acute respiratory syndrome coronavirus 2 to patients and health care staff. Future larger studies should investigate the cost-effectiveness of telemedicine used to triage surgical from nonsurgical patients, potential cost-savings from reducing travel burdens and lost work time, improved access, reduced wait times, and impact on patient satisfaction.Lambert-Eaton myasthenic syndrome (LEMS) is a rare, autoimmune or paraneoplastic condition characterized by muscle weakness and fatigability. In cancer therapy, immune checkpoint inhibitors (ICI) sensitize the immune system for tumor antigens. We report a 62-year-old, female patient with paraneoplastic LEMS as first manifestation of Merkel cell carcinoma. Under avelumab, the LEMS exacerbated with worsening of limb weakness and a severely reduced vital capacity ( less then  1 l). To treat this immunological side effect, we added a regimen with intravenous immunoglobulins. Hereby, the LEMS improved significantly. As we were able to continue the cancer treatment, the Merkel cell carcinoma has been in remission so far. This is the first description of paraneoplastic LEMS, avelumab, and Merkel cell carcinoma. We conclude that immunoglobulins are an option to control an ICI-associated deterioration of paraneoplastic symptoms.
