The Universidade Federal de Santa Maria is a Brazilian public university located in Santa Maria, in the state of Rio Grande do Sul, funded by the federal government of Brazil. It was founded in 1960, by Professor José Mariano da Rocha Filho.UFSM's presence in the municipality of Santa Maria is one of the reasons why the city is sometimes called "university city" or "culture city". Santa Maria is located in western Rio Grande do Sul, approximately 290 km far from the capital city of the state, Porto Alegre. Set in the heart of the pampas of Brazil, the city thrives with gaúcho culture.UFSM is a public, free university, and students do not pay any tuition fees. It is the oldest federal university not located in a Brazilian state capital city, and the largest in number of undergraduate courses offered in Rio Grande do Sul state. Wikipedia.

A study in rats, published in Experimental Physiology, showed that resistance exercise recovers memory and motor impairment caused by the flavour enhancer monosodium glutamate. Monosodium glutamate (MSG) is an additive that mimics umami flavour, the fifth taste aside from sweet, sour, salty and bitter. Some studies have shown MSG to have adverse effects in humans, making it important to understand how it works in the body. Giving MSG to new-born rats has previously been shown to cause motor and memory impairment. The team of researchers at the Federal University of Santa Maria in Brazil gave the experimental group of new-born rats a dose of MSG. This dose is not comparable to the dose humans eat. Of the rats that were given MSG, half began a resistance exercise regimen at two months of age. The exercise consisted of climbing a ladder at an 80 degree angle. The rats performed these exercises five times per week for seven weeks. After resistance exercise, researchers tested the rats' motor coordination and memory. Within the group injected with MSG, motor coordination was less impaired in both male and female rats that performed resistance exercise. Memory also improved in both male and female rats, but it was a different type of memory in the two sexes. Recognition memory improved in male rats, whereas female rats had improved location memory. To test both types of memory, researchers present rats with two objects. To test recognition memory, one object is replaced with a new one. To test location memory, one object is moved to a new location. The next question that Cristina Wayne Nogueira, lead investigator, and her team will explore is the mechanism of memory improvement. Commenting on the study, Nogueira said: 'This study highlights that resistance-based exercise improves cognitive deficit induced by a flavour enhancer. Our next goal is to understand how this is happening.'

When a small spider eats up a snake, it makes the news. This is what happened in Brazil when a Tarantula spider devoured a snake under a rock. This surprised scientists at the Federal University of Santa Maria, who were searching for Tarantulas in Serra do Caverá in Southern Brazil, when they spotted the rare "dinner" live. The victim was an Almaden ground snake, which is about a foot in length. The researchers saw the Tarantula — Grammostola quirogai — chomping down the snake — Erythrolamprus almadensis, and reported their observations in the journal Herpetology Notes. Brazil's Serra do Caverá is known to house many species of Tarantula, particularly sedentary females that live in the rocks. "Most likely, the snake was surprised upon entering the spider's environment and hence was subdued by it," said the researchers. The study's first author Leandro Malta Borges, a graduate student at the Federal University who also witnessed the horrible dinner live, is credited with many papers in Herpetology Notes about lizards and amphibians being eaten up by bugs. Borges also studied Aglaoctenus oblongus, a spider that was seen eating up a tree frog. According to Borges, the high surprise in the incident is the size of the snake versus the tiny size of the predator spider, which is just a fraction of the former. The grisly discovery is perhaps the first ever recorded evidence of a Tarantula eating a snake in the wild. "To the best of our knowledge, we present here the first documented case involving the predation of a snake by an individual of the Theraphosidae family in nature," the researchers noted. The snake had a snout-vent length 390.60 mm with most damage to the middle and anterior regions of the victim's body. The snake's body was in a state of decomposition due to the extracorporeal digestion process executed by the arachnid. Cases of captive Tarantulas occasionally eating snakes were reported in 1926 by Brazilian researchers Jehan Vellard and Vital Brazil. "They eat pretty much anything they can grab and overpower," noted Chris Hamilton, a Tarantula expert, and researcher at the Florida Museum of Natural History. It is likely that the snake sneaked into the Tarantula's rock in a bid to use it as a den or simply slithered by it. The fatal attack of the Tarantula must have come from the less than an inch long fangs usually used in subduing preys. When the researchers saw the spider, it was consuming the snake's body after liquefying it like a goo for making it more digestible. Borges noted that some spiders, such as the black widow, are known for feeding on snakes, with their webs for capturing and strong toxin for killing. © 2017 Tech Times, All rights reserved.

Synthesis of heterocycles through electrophilic cyclization of alkynes containing heteroatom was reported. These heterocycle rings can be formed through endo or exocyclization modes, depending on the chain length, the substitution pattern on the chain, and the electrophile employed. Starting from 5-substituted Z-enynoic acids 5, the construction of 6-iodopyranones 6 and iodoylidenefuranones 7, in which furanones 6 are the major products, was developed by employing 3 equiv of iodine and 3 equiv of NaHCO3 in CH3CN. The selectivity and the yields of these cyclizations were significantly affected rather by the temperature than the electrophilic sources and nature of these benzoates. Thus, by using 1.0 equiv of ICl as electrophilic source in CH2Cl2, at room temperature, the Z-enynoic acids 5 afforded a 72:28 ratio of lactones 6 and 7. Larock and co-workers subjected a series of acetylenic esters and acids as substrates to the electrophilic cyclization conditions in the preparation of 2(3H)-furanones.


The habitat loss or fragmentation and reduced connectivity between habitats are common features in areas with roads. These impacts have close liaison with trampling of wild vertebrates. This study aimed to identify and quantify the factors that influence directly and indirectly these accidents. Four sections (North, South, East and West) at 100 km of highway BR 158, 287, 392 and RST 241 were monitored, through a different route every week in each trip, totaling 48 in the period from December 2008 to December 2009. The starting point of the routes was the outskirts of Santa Maria, zero km of the route, returning by the same BR occurred after traveling 100 km on the highway. 829 individuals were recorded, belonging to four classes, 43 families and 83 species. The percentage of roadkill mammals was 51.6%; 31.9% of birds; 11.7% of reptiles; and 4.7% of amphibians. The sampling effort of 9600 km resulted in an average of 0.086 roadkill/km. The most roadkilled vertebrates were in the class of mammals the possum-to-ear-White (Didelphis albiventris), 135 records; in birds, eared dove (Zenaida auriculata), with 39 records; in reptiles, tegu lizard (Tupinambis merianae), with 42 records; and amphibians in the frog cururu (Rhinella icterica), with 20 animals. The events were affected by seasonality, type of matrix surrounding the accident, the rainfall and temperature. No effective mitigation measures were identified on the slopes. Installation media for the implementation of highways by wildlife in identified critical areas was suggested. However, more studies are needed in order to identify specific features of the highways and species that are present in the region. © 2012 by Unisinos.

The ovine conceptus releases interferon-tau (IFNT), which prevents upregulation of the endometrial estrogen receptor (ESR1) and, consequently, oxytocin receptor (OXTR), thereby disrupting pulsatile release of prostaglandin F2alpha (PGF) in response to oxytocin. IFNT, through paracrine action on the endometrium, protects the corpus luteum (CL) during maternal recognition of pregnancy. Pregnancy also induces IFN stimulated genes (ISGs) in peripheral blood mononuclear cells (PBMCs), which is interpreted to reflect a "prompted" antiviral and immune cell response peripherally in ruminants. IFNT was recently demonstrated to be released from the uterus in amounts of 200 microg (2 x 10(7) U)/24 h via the uterine vein and to induce ISGs in the CL during maternal recognition of pregnancy. Delivery of recombinant ovine (ro) IFNT into the uterine vein in a location that is upstream of the utero-ovarian plexus from Day 10 to 17 maintained serum progesterone concentrations and extended normal 16-17 d estrous cycles to beyond 32 d. It is concluded from these studies that IFNT is released into the uterine vein and initiates a peripheral antiviral response to protect pregnancy from maternal viral infection. It also may have endocrine action through inducing luteal resistance to PGF and longer-term survival of the CL and maintenance of pregnancy.

Cyprinus carpio were exposed under field conditions to 20.87 microg l(-1) of commercial herbicide bispyribac-sodium (Nominee, SC), during 7, 21 and 72 days. Enzymatic parameters such as catalase (CAT), glutathione S-transferase (GST) and acetylcholinesterase (AChE) activities, as well as thiobarbituric acid-reactive substances (TBARS) and protein carbonyl contents were studied in different tissues. After 7 days of exposure, GST activity decreased. At the same period, brain AChE activity increased, but a reduction of activity was observed in muscle tissue. Brain TBARS levels increased at 7 days. After 21 days of exposure liver CAT levels and muscle AChE activities decreased. In the same period, liver protein carbonyl and muscle TBARS increased. After 72 days of exposure in the field, AChE activity was reduced in both brain and muscle. Protein carbonyl contents in liver and brain TBARS levels increased. Muscle AChE activity, TBARS and protein carbonyl can be used as biomarkers of exposure to the herbicide bispyribac-sodium. This study demonstrates effects of exposure to bispyribac-sodium under rice field conditions on oxidative stress parameters in tissues of Cyprinus carpio. (c) 2010 John Wiley & Sons, Ltd.
