A case control study of acute leukemia risk factors in adults, Shiraz, Iran.

Abstract: Background: Leukemia is one of the most common cancers in Iran. Few studies have focused on identifying the causative factors for leukemia. This implies the necessity of this case-control study. This study was undertaken to identify possible risk factors associated with leukemia. Materials and Methods: In a case-control study matched by age and sex. 100 leukemic patients admitted in hematology wards in Namazee Hospital affiliated to Shiraz University of Medical Sciences were enrolled. Control group compromised 100 ..

Associations among milk production traits and glycosylated haemoglobin in dairy cattle: importance of lactose synthesis potential

Abstract Glucose is the major precursor of lactose synthesis in the mammary gland. Lactose the major carbohydrate and osmolyte of milk, controls milk volume and its concentration. Glycosylated haemoglobin (HbG) is a retrospective measure of mean blood glucose level and it is largely unaffected by recent physiological conditions and environmental events. The purposes of this study were to determine the correlations between lactose traits and other milk production traits in dairy cattle and to investigate whether HbG level can be correlated with milk and lactose production traits. Here, HbG percentage, milk and lactose production traits including milk yield, lactose, protein, SNF, total solid and fat percentages and yields were measured in 485 second calved Iranian Holstein cattle. Statistically significant negative correlations were established between HbG and milk yield (r=−0.88), lactose yield (r=−0.83), SNF yield (r=−0.81), protein yield (r=−0.79) and total solid yield (r=−0.74). Positive correlations were established between lactose yield and milk (r=0.96), protein (r=0.81), SNF (r=0.92) and total solid (r=0.79) yields. The negative correlation between HbG and milk and total lactose production is probably related to the higher glucose demands in the lactating mammary gland of more productive cows. The positive correlation between lactose yield and milk, protein, SNF and total solid yield indicates that the level of lactose synthesis influences milk production traits in ways other than merely via its osmolytic action

Topiramate Induced Acute Angle Closure Glaucoma

Topiramate is an oral sulphamate medication primarily used for seizure, migraine and neuropathic pain. It has been associated with secondary angle closure, which can mimic acute angle closure glaucoma. Suspicion for medication induced angle closure glaucoma should be higher whenever angle closure presents bilaterally. We present two cases of bilateral angle closure glaucoma secondary to topiramate

Soy protein–gum karaya conjugate: emulsifying activity and rheological behavior in aqueous system and oil in water emulsion

The main objective of this study is to investigate the effects of mixing and conjugation of soy protein isolate (SPI) with gum karaya on the characteristics of the hybrid polymer (protein–gum) in both aqueous systems and oil-in-water (O/W) emulsions. It was hypothesized that the covalent linkage of gum karaya with SPI would improve the emulsifying activity and rheological properties of both polymers. Conjugation occurred under controlled conditions (i.e., 60 °C and 75 % relative humidity, 3 days). The conjugated hybrid polymer produced smaller droplet with better uniformity, higher viscosity and stronger emulsifying activity than native gum karaya, suggesting the conjugated polymer provided a bulkier secondary layer with more efficient coverage around oil droplets, thereby inducing stronger resistance against droplet aggregation and flocculation. Emulsions containing the native gum karaya produced the largest droplet size among all prepared emulsions (D 3,2 = 8.6 μm; D 4,3 = 22.4 μm); while the emulsion containing protein–gum conjugate (1:1 g/g) had the smallest droplet size (D 3,2 = 0.2 μm; D 4,3 = 0.7 μm) with lower polydispersity. The protein–gum conjugate (1:1 g/g) also showed the highest elastic and viscous modulus, the lowest polydispersity (span) and the highest emulsifying activity among all native, mixed and conjugated polymers. Therefore, the percentage of gum karaya used for production of O/W emulsion can be decreased by partially replacing it with the conjugated gum

An Investigation into Attitudes towards Learning English and the Motivation Type (Integrative vs. Instrumental) in Iranian Students at Universiti Kebangsaan Malaysia

Learning a second language is of paramount importance as it equips one with the ability to communicate with people of other cultures. There are some factors that affect the success of learning a new language. The most omnipresent of all are students‟ attitudes and motivation. L2 learners‟ motivation helps them move forward and make progress and is deemed to be the key to successful language learning. Motivation for learning a language can have a variety of natures, the most important of which being „instrumental‟ and „integrative‟. Some students strive to learn a language for practical purposes such as entering college or meeting some requirements (i.e. instrumental) whereas others have an affinity for a particular language or for identifying with its native speakers (integrative). This study encompassed Iranian postgraduate students who were studying in Universiti Kebangsaan, Malaysia (UKM), doing either their master‟s or PhD in a variety of majors. The objective was to shed light on their attitudes towards learning English, the second language studied there, and the comparative nature of their motivation, in terms of being instrumentally or integratively oriented. Using a number of instruments, it came to light that those students had highly positive attitudes towards learning English. Moreover, results showed that they had high levels of both integrative and instrumental motivations although the instrumental motivation outweighed the other type. Stated differently, the majority of students were interested in learning English mainly to get a better job or to pursue their studies at a higher degree

Nucleotide sequence of cDNA encoding for preprochymosin in native goat (Capra hircus) from Iran

Summary Prochymosin is one of the most important aspartic proteinases used as a milk-clotting enzyme in cheese production. In the present investigation we report sequence of cDNA encoding goat (Capra hircus) preprochymosin and compare its nucleotide and deduced amino acid sequences with sequences of other ruminants preprochymosin. As bovine prochymosin, the caprine prochymosin cDNA encodes 365 amino acids with a prosegment of 42 amino acids and the mature goat chymosin begins with glycine. The preprochymosin nucleotide sequence reported in this study differs from other reported goat sequence (AY389343) in three nucleotides, two of which alter the amino acids at positions 19p and 139

Impaired Hepatocyte Regeneration in Toll-Like Receptor 4 Mutant Mice

Multiple lines of evidence suggest a role for endogenous lipopolysaccharides in toxin-induced liver injury. Toll-like receptor 4 has recently been implicated as a cell surface receptor important for lipopolysaccharide responsiveness. In these experiments, we sought to determine the role of toll-like receptor 4 in acute liver injury by carbon tetrachloride by utilizing the naturally occurring toll-like receptor 4 mutant and wild-type mice strains. Mice were injected with either carbon tetrachloride or the carrier. Serum transaminase levels peaked at 24 hr after carbon tetrachloride administration for both wild-type and mutant mice, with no significant histological difference in initial liver injury between the two groups. However, an overall decrease in hepatocyte proliferation was found in the mutant mice. Examination of the liver tissue revealed significant decreases in intrahepatic expressions of proinflammatory mediators. In conclusion, our results suggest that toll-like receptor 4 is important in the hepatic regenerative response to CCl 4 liver injury via its role in modulating the inflammatory response to hepatic injury.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/44432/1/10620_2004_Article_490703.pd
