Texel (sheep)
The Texel is a breed of domestic sheep originally from the island of Texel in the Netherlands. A heavily muscled sheep, it produces a lean meat carcass and will pass on this quality to crossbred progeny. The wool is around 32 micrometres and is mostly used for hosiery yarns and knitting wools. It is presently a popular lean meat sheep across Europe, as well as Australia, New Zealand and the United States. History The Texel sheep originated on the island of Texel, the largest of the Wadden Islands off the north coast of the Netherlands. The exact origin of the breed is unknown although it is thought to be a cross of the original Texel sheep with multiple English breeds. It was slowly bred into a meat breed of outstanding carcass quality. It is now one of the most common meat breeds in the Netherlands, making up seventy percent of the national flock. United Kingdom In the early 1970s, the superior quality of the Dutch Texel caught the attention of some English breeders who ...

Blue Texel
The Blue Texel is a Dutch breed of meat sheep. It is a colour variety of the Texel, which originates on the island of Texel in the Wadden Sea. It was established as a separate breed in 1983. History The Blue Texel was first registered and recorded in the early 1970s in Holland when a blue lamb was born to white Texel Texel (; Texels dialect: ) is a municipality and an island with a population of 13,643 in North Holland, Netherlands. It is the largest and most populated island of the West Frisian Islands in the Wadden Sea. The island is situated north of Den ... parents. After this occurred, Texels were deliberately bred to give birth to blue lambs. By 1983 there were 11 flocks with a total of 213 blue texel sheep.

Beltex
The Beltex is a breed of heavily muscled domestic sheep. A portmanteau of Belgian and Texel, the name reflects the breed's origin as an offshoot of Texel sheep from The Netherlands. In the late 1980s, Belgian Texels were exported to the United Kingdom, and it was there that it was primarily refined into its modern form. It is primarily used in Europe as a terminal sire, meaning Beltex rams are prized for mating with ewes to produce lambs for meat. Characteristics The Beltex is a white faced sheep with medium-length wool. It is best known for its extremely heavy muscling, especially in the hindquarters. Rams on average weigh and ewes at maturity. At the withers, rams grow to and ewes at maturity.

Mir-1 MicroRNA Precursor Family
The miR-1 microRNA precursor is a small micro RNA that regulates its target protein's expression in the cell. microRNAs are transcribed as ~70 nucleotide precursors and subsequently processed by the Dicer enzyme to give products at ~22 nucleotides. In this case the mature sequence comes from the 3' arm of the precursor. The mature products are thought to have regulatory roles through complementarity to mRNA. In humans there are two distinct microRNAs that share an identical mature sequence, and these are called miR-1-1 and miR-1-2. These micro RNAs have pivotal roles in development and physiology of muscle tissues including the heart. MiR-1 is known to play an important role in heart diseases such as hypertrophy, myocardial infarction, and arrhythmias. Studies have shown that MiR-1 is an important regulator of heart adaption after ischemia or ischaemic stress and it is upregulated in the remote myocardium of patients with myocardial infarction. Also MiR-1 is downregulated in myo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MicroRNA
MicroRNA (miRNA) are small, single-stranded, non-coding RNA molecules containing 21 to 23 nucleotides. Found in plants, animals and some viruses, miRNAs are involved in RNA silencing and post-transcriptional regulation of gene expression. miRNAs base-pair to complementary sequences in mRNA molecules, then gene silence said mRNA molecules by one or more of the following processes: (1) cleavage of mRNA strand into two pieces, (2) destabilization of mRNA by shortening its poly(A) tail, or (3) translation of mRNA into proteins. This last method of gene silencing is the least efficient of the three, and requires the aid of ribosomes. miRNAs resemble the small interfering RNAs (siRNAs) of the RNA interference (RNAi) pathway, except miRNAs derive from regions of RNA transcripts that fold back on themselves to form short hairpins, whereas siRNAs derive from longer regions of double-stranded RNA. The human genome may encode over 1900 miRNAs, although more recent analysis sugges ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myostatin
Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a protein that in humans is encoded by the ''MSTN'' gene. Myostatin is a myokine that is produced and released by myocytes and acts on muscle cells to inhibit muscle growth. Myostatin is a secreted growth differentiation factor that is a member of the TGF beta protein family. Myostatin is assembled and produced in skeletal muscle before it is released into the blood stream. Most of the data regarding the effects of myostatin comes from studies performed on mice. Animals either lacking myostatin or treated with substances that block the activity of myostatin have significantly more muscle mass. Furthermore, individuals who have mutations in both copies of the myostatin gene have significantly more muscle mass and are stronger than normal. There is hope that studies into myostatin may have therapeutic application in treating muscle wasting diseases such as muscular dystrophy. Discovery and sequenci ...

Three Prime Untranslated Region
In molecular genetics, the three prime untranslated region (3′-UTR) is the section of messenger RNA (mRNA) that immediately follows the translation termination codon. The 3′-UTR often contains regulatory regions that post-transcriptionally influence gene expression. During gene expression, an mRNA molecule is transcribed from the DNA sequence and is later translated into a protein. Several regions of the mRNA molecule are not translated into a protein including the 5' cap, 5' untranslated region, 3′ untranslated region and poly(A) tail. Regulatory regions within the 3′-untranslated region can influence polyadenylation, translation efficiency, localization, and stability of the mRNA. The 3′-UTR contains both binding sites for regulatory proteins as well as microRNAs (miRNAs). By binding to specific sites within the 3′-UTR, miRNAs can decrease gene expression of various mRNAs by either inhibiting translation or directly causing degradation of the transcript. The 3†...

Semen Collection
Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination, or medical study (usually in fertility clinics). Semen can be collected via masturbation (e. g., from stallions and canids), prostate massage, artificial vagina, penile vibratory stimulation (vibroejaculation) and electroejaculation. Semen can be collected from endangered species for cryopreservation of genetic resources. By species Humans Methods of semen collection from humans include: * Masturbation, directing the sample into a clean cup. This is the most common way to collect a semen sample. * Sexual intercourse using a special type of condom known as a collection condom. Collection condoms are made from silicone or polyurethane, as latex is somewhat harmful to sperm. Many men prefer collection condoms to masturbation, and some religions prohibit masturbation entirely. Adherents of religions that prohibi ...
