BACKGROUND Cyclooxygenase-2 (COX-2) is an enzyme involved in the synthesis of prostaglandins and thromboxanes, which are regulators of processes that are relevant to cancer development. It is involved in carcinogenesis, immune response suppression, apoptosis inhibition, angiogenesis, and tumor cell invasion and metastasis. The gene for COX-2, designated as prostaglandin-endoperoxide synthase 2 ...

Previous studies showed that suppressor of cytokine signaling 3 (SOCS3) protein is associated with incidence and progression of hepatocellular carcinoma (HCC); however, the association between the genetic polymorphism of SOCS3 gene and HCC remains unknown. A total of 254 HCC patients and 354 healthy controls were enrolled. All HCC patients underwent partial hepatectomy as initial treatment and ...

BACKGROUND AND PURPOSE Recent findings of an association between a functional toll-like receptor 4 (TLR4) D299G gene variant and reduced risk of atherothrombotic disorders have generated great interest. METHODS We evaluated the TLR4 D299G polymorphism among 695 individuals with incident myocardial infarction (MI) or stroke and among 695 age- and smoking-matched individuals who remained free o...

Primary dysmenorrhea (PDM), the most prevalent menstrual cycle-related problem in women of reproductive age, is associated with negative moods. Whether the menstrual pain and negative moods have a genetic basis remains unknown. Brain-derived neurotrophic factor (BDNF) plays a key role in the production of central sensitization and contributes to chronic pain conditions. BDNF has also been impli...

spinal muscular atrophy (sma) is a common autosomal recessive neuromuscular disorder caused by the loss of α-motor neurons in the spinal cord. the survival motor neuron (smn) protein is encoded by 2 genes, smn1 and smn2. the most frequent mutation is the biallelic deletion of exon 7 of the smn1 gene. smn2 cannot compensate for the loss of smn1, due to the exclusion of exon 7. carrier frequency ...

background: metabolic syndrome (mets) is a prevalent disorder in pediatric age groups, described by a combination of genetic and environmental factors. sterol regulatory element‑binding transcription factor 1 (srebf‑1) induces the expression of a family of genes involved in fatty acid synthesis. moreover, dysregulation of mir‑33b, which is located within the intron 17 of the srebf‑1 gene, disru...

Amplitude modulation (AM) detection was measured with a short (50 ms), high-frequency carrier as a function of carrier level (Experiment I) and modulation frequency (Experiment II) for conditions with or without a notched-noise precursor. A longer carrier (500 ms) was also included in Experiment I. When the carrier was preceded by silence (no precursor condition) AM detection thresholds worsene...

-In this paper, we propose iterative soft-input soft-output (SISO) multi-carrier detection (inter-carrier interference cancellation) and LDPC decoding of the OFDM system in the mobile channel. The proposed SISO multi-carrier detection and sum-product decoding of the LDPC-coded OFDM system can achieve better error rate performance than previous SISO multi-carrier detection and BCJR decoding of c...

Glycogen storage disease type III (GSD-III), an autosomal recessive disease, is caused by deficient glycogen debranching enzyme (GDE) activity. We identified three polymorphic markers in the GDE gene using single strand conformation polymorphism (SSCP) analysis and DNA sequencing. They were -10G/A in the 5' non-translated region of exon 3,2001 + 8C/T in intron 16, and 3199C/T (P1067S) in exon 2...
