ObjectiveTo screen pregnant women at risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection during delivery using reverse-transcription polymerase chain reaction (RT-PCR) test and serum immunoglobulin (Ig) testing.MethodBetween March 31 st August 2020, consecutive admitted for labor in a single hospital were screened SARS-CoV-2 with nasopharyngeal RT-PCR swab tests detec...

Flavones are belonging to flavonoids group and show diverse biological functions. Therefore, they have much attention as drugs for maintaining human health via contributing prevention treatment of various diseases like cancers, diabetes, neurodegenerative diseases, ischemic stroke, inflammation cardiovascular diseases. On the other hand, monoblastic leukemia U937 cells been used an excellent in...

AIM To investigate the association between the quantity of gastric chemokine mRNA expression, severity of gastritis, and cagA positivity in Helicobacter pylori associated gastritis. METHODS In 83 dyspeptic patients, antral and corpus biopsies were taken for semiquantitative reverse transcription polymerase chain reaction (RT-PCR) and histological grading of gastritis. Gastritis was evaluated ...

PURPOSE To increase the database of genes expressed in human cornea and to gain insights into the molecular basis of keratoconus (KC). METHODS A cDNA library was constructed from KC corneas harvested at keratoplasty and used for expressed sequence tag (EST) analysis. Data were analyzed using grouping and identification of sequence tags (GRIST). Expression of selected clones was examined by RT...

CONTEXT Despite the advances in the cure rate for acute lymphoblastic leukemia, approximately 25% of affected children suffer relapses. Expression of genes for the multiple drug resistance protein (MDR-1), multidrug resistance-related protein (MRP), and lung resistance protein (LRP) may confer the phenotype of resistance to the treatment of neoplasias. OBJECTIVE To analyze the expression of t...

PURPOSE To detect mRNAs for somatostatin (somatotropin release-inhibiting factor [SRIF]) receptor subtypes 1 to 5 (sst(1) through sst(5)) in rabbit retinas by reverse transcription-polymerase chain reaction (RT-PCR) and to investigate the distribution of sst(1) by single- and double-label immunocytochemistry. METHODS Semiquantitative RT-PCR using sst-specific primers from mouse sequences was ...

Orexins and their receptors OX1 and OX2 regulate energy balance and the sleep-wake cycle. We studied the expression of prepro-orexin (PPO), OX1, and OX2 in brain and pituitary under the influence of the hormonal status in adult rats. Primarily, PPO, OX1, and OX2 expression was determined in Sprague-Dawley female cycling rats during proestrus and in males. Animals were killed at 2-h intervals. A...

background and objectives : each year, enteroviruses infect millions of people and cause different diseases. the agents are usually detected using cell culture. rd (rhabdomyosarcoma) and l20b (l cells) are among the recommended cells by the world health organisation (who) for this purpose. even though cell culture is the most common method used in diagnosing enteroviruses in stool specimens, th...

human growth hormone (hgh) genomic sequence containing 5 exons and 4 introns was cloned in pcdna-3 and the constructed plasmid was subsequently used for transfection ofnlli-3t3 cell line using lipofection technique. expression of hgh in stably transfected cells was assayed using elisa. total rna was extracted from transfected cells and hgh cdna was amplified by rt-pcr using specific primers. th...
