Pharmacological Properties of Edible Asparagus acutifolius and Asparagus officinalis Collected from North Iraq and Turkey (Hatay)
In this study, antioxidant, oxidant, antimicrobial, and antiproliferative activities of Asparagus acutifolius L. and Asparagus officinalis L., known for their nutritional properties, were determined. In this context, methanol (MeOH) and dichloromethane (DCM) extracts of plants were obtained. Total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) were determined using Rel Assay kits. Antimicrobial activities of plant extracts were determined against the test microorganisms using the agar dilution method. Antiproliferative activity was tested on the lung cancer cell line A549. As a result of the studies, it has been determined that the plant species have high antioxidant potential. In addition, it was observed that the antifungal potentials of plant extracts are high. Antiproliferative activity was determined to be at high level in both plant species. As a result, it has been determined that A. acutifolius and A. officinalis have medical potential and can be used as natural agents in pharmacological designs
TRP genes family expression in colorectal cancer
Colorectal cancer (CRC) is the most common cancer of the gastrointestinal tract. Different factors are responsible for the development of CRC. Transient Receptor Potential (TRP) which is an important component of calcium channel is associated with several pathological conditions like cancer, neurodegenerative and cardiovascular diseases. Thirty members of the family of TRP ion channel in mammals have been determined till now. The aim of this study is to investigate TRPM, TRPV and TRPC gene expression levels in tumor tissues of CRC patients and to analyze the relationship of expression in tumor tissue of CRC with other known prognostic factors. Material and Methods: In this study, 93 CRC patients were included. The level of TRP gene expression in paraffin blocks of normal and cancerous colorectal tissue samples were studied at the level of mRNA with Real-time PCR. Results: The mRNA expression level of TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 genes in 37 female and 56 male patients diagnosed with CRC was revealed lower in tumor tissue as compared to normal tissue (p < 0.05). No statistically significant differences of mRNA expression levels of other TRP genes were found. Conclusions: TRP gene family like TRPV3, TRPV4, TRPV5, TRPM4 and TRPC6 may be thought as potential genes contributing to tumorigenesis as their expression decreases in CRC as compared to normal tissues. Key Words: colorectal cancer, TRP genes family: TRPV3, TRPV4, TRPV5, TRPM4, TRPC6, mRNA expression
Expression profiling of SCN8A and NDUFC2 genes in colorectal carcinoma
The expression differences of SCN8A (which encodes type VIII alpha subunit of voltage gated sodium channel) and NDUFC2 (which encodes C2 subunit of Complex I enzyme in oxidative phosphorylation) genes were evaluated in paired colorectal cancer (CRC) tissues which was relied on our partial transcriptome analysis data in cancer cell lines. Materials and Methods: A total of 62 paired tissues of CRC patients (34 male, 28 female) were included in the study. The mRNA levels of SCN8A and NDUFC2 genes were determined by using real-time PCR (qRT-PCR and semiquantitative PCR). Results: SCN8A gene expression level was significantly lower in tumor tissues (p = 0.0128) and in the patients with the age below 45 years (p = 0.0049). There were also meaningful relationships between the gender, grade of CRC, tumor location, histopathological classification, and SCN8A expression. There was no NDUFC2 differential expression. However, the tumors taken from right colon had significantly lower NDUFC2 expression. Conclusion: Although the voltage gated sodium channels (VGSCs) and Complex I (CI) were associated to a number of diseases including different types of cancers, the different subunits of CI and individual members of VGSCs seem to be cancer type-specific in varying proportions.

Diagnostic value of serum glial fibrillary acidic protein and S100B serum levels in emergency medicine patients with traumatic versus nontraumatic intracerebral hemorrhage
Background: Glial fibrillary acidic protein (GFAP) is a brain‑specific astroglial protein that is released into the blood soon after traumatic brain injury by mature astrocytes. S100B is rapidly released into the cerebrospinal fluid and bloodstream after brain damage. We compared the serum concentrations of these proteins inpatients with severe head trauma (bleeding and/or fracture) or nontraumatic intracerebral hemorrhage and healthy individuals.Materials and Methods: The study included 63 patients (33 males and 30 females) with traumatic cerebral hemorrhage and/or cranial bone fractures or nontraumatic cerebral hemorrhage and 30 healthy control subjects. The reasons for attending the emergency department were as follows: fall from a height (n = 32), traffic accident (n = 18), nontraumatic intracerebral hemorrhage (n = 6), animal kick to the head (n = 4), and blow to the head (n = 3).Results: Of the 63 patients included in the study, 33 (52.4%) were male and 30 (47.6%) were female. Of the 30 healthy controls, 12 (40%) were male and 18 (60%) were female. The average age of the patients was 27 years (range, 1 month to 86 years) and the average age of the control group was 21 years (range, 18–30 years). The mean serum GFAP concentrations were 86.37 ng/mL in the patients and 38.07 ng/mL in the controls (P < 0.05). The mean serum S100B concentrations were 428.37 pg/mL in the patients and 103.44 pg/mL in the controls (P < 0.05). Eight (12.7%) patients died in the hospital; of those, the mean GCS score was 4.6, and the mean GFAP and S100B levels were 127.8 ng/mL and 860.6 pg/mL, respectively.Conclusion: The GFAP and S100B concentrations were significantly higher in patients with traumatic or nontraumatic brain injury than in healthy individuals, indicating that serum levels of these biomarkers may provide an alternative to computed tomography for the diagnosis of brain injury.Keywords: Fracture, glial fibrillary acidic protein, hemorrhage, S100
