Evaluation of XRCC2 Expression in Breast Cancer

2024-07-20T19:57:34+03:00

Breast cancer (BC) is a leading cause of mortality among women worldwide. The X-ray repair cross-complementing group 2 (XRCC2) gene is implicated in DNA repair processes, and its role in BC remains controversial. This study aimed to analyze XRCC2 mRNA expression in BC tissues compared to normal breast tissues to elucidate its potential role in BC pathogenesis. An observational analytical study with a case-control design was conducted at Zheen International Hospital, Erbil, Iraq, from 2021 to 2024. The study included 44 adult women diagnosed with BC, and XRCC2 mRNA levels were measured using real-time quantitative reverse transcription PCR (qRT-PCR). RNA was extracted, converted to cDNA, and analyzed by qRT-PCR. The XRCC2 mRNA expression levels were normalized using GAPDH and statistically analyzed using the 2−ΔCt method. The study found a significant upregulation of XRCC2 expression in BC tissues compared with normal controls (p<0.05), especially in patients aged 40-55 years and those > 56 years (p=0.0392 and p=0.0191, respectively), and in higher BC grades II and III (p=0.0013 and p=0.0051, respectively). Invasive ductal carcinoma exhibited a notable increase in XRCC2 expression (p=0.0006). In conclusion, the increased XRCC2 mRNA expression in BC tissues suggests a possible oncogenic role of XRCC2 in BC development. The correlation between age and cancer grade indicates its potential as a marker for BC progression.

2024-07-20T20:42:14+03:00

Otak-otak is well-known as a traditional local food in Malaysia. It is made from fish meat, tapioca flour, and many spices. This study investigates the effect of corn cob powder and oat fibre incorporation on the physicochemical properties and sensory acceptance of otak-otak with different formulations. The formulations used control A (100% tapioca flour), B (0% CCP: 100% oat fibre), C (25% CCP: 75% oat fibre), D (50% CCP: 50% oat fibre), E (75% CCP: 25% oat fibre), and F (100% CCP: 0% oat fibre). The proximate analysis showed that otak-otak incorporated with CCP and oat fibre significantly differed (p<0.05) regarding crude fibre and fat. Physical analysis showed that the colour of the otak-otak for L* value ranges from 53.71 to 57.58, a* value ranges from 13.15 to 15.10, b* value ranges from 32.80 to 35.21 and the ΔE 0.96 to 4.86. For texture profile analysis, the hardness ranges from 2147.60 to 5006.00 (g), springiness ranges from 0.39 to 0.66 (mm), cohesiveness ranges from 0.35 to 0.48, and chewiness ranges from 370.40 to 1459.90 (gf). For sensory evaluation, the control formulation still the highest chosen by the panellist but has no significant difference (p<0.05) with formulation E (75% CCP: 25% oat fibre) and formulation C (25% CCP: 75% oat fibre). Therefore, from this study, we successfully developed otak-otak by adding corn cob powder and oat fibre.

Peptide Analysis of Protein Extracts from Caulerpa Lentillifera by Nano LC-ESI-Ms/Ms and Their Potential as Precursor of Biologically Active Peptides – In Silico Approach

2024-07-20T21:15:55+03:00

Peptidomics research is gradually positioning in food science fields due to an increasing interest in peptides released from food proteins with health benefits and nutraceutical properties. Referable to the complexity of these compounds, their study requires advanced analytical techniques such as tandem mass spectrometry. Seaweed naturally has high nutritional value and many health-promoting effects. Hence, this work aimed to characterize the peptide and to virtual screening for their potential as a precursor of biologically active peptides. The total soluble protein was extracted from Caulerpa lentillifera using the phenol ammonium acetate precipitation method. In solution, digestion was carried out using trypsin on 500 µg of protein. Peptide sequencing was accomplished using nano liquid chromatography-electrospray ionization tandem mass spectrometry (nLC-ESI-MS/MS), and Peaks Studio 7 was used for the analysis of MS/MS data and de novo peptide sequencing using an average local confidence above 90%. The results showed that 76 peptides mapped to selected proteins and 145 were de novo peptide sequences. In silico approaches of both peptide sequences resulted in 15 types of biological activity characteristics of peptides from among 44 categories as listed in the BIOPEP-UWM database, and motifs with the ACE inhibitory activity occur most frequently. These findings are relevant to the search for bio-functional ingredients as constituents of functional foods or provide added value to nutraceutical foods. Significantly, the methodology described here might apply to discovering the potential in any organism with incomplete genome data.

Age-Specific Reference Values for Free Carnitine and Short Chain Acylcarnitines Content in Dried Blood Spots in Newborns in Western Kazakhstan: A Tandem Mass Spectrometry Measurement

2024-08-31T23:26:26+03:00

Sodium-dependent multivitamin transporter (SMVT) deficiency is a recently described multivitamindependent inherited metabolic disorder (IMD). SMVT is encoded by the SLC5A6 gene located on chromosome 2p23.3. We describe a clinical case of SMVT deficiency in a child with developmental delay, microcephaly, persistent neurological symptoms, skin lesions and frequent upper respiratory tract infections. A tandem mass spectrometry study of the metabolic profile of amino acids and acylcarnitines, carried out twice, showed increased blood levels of methylmalonylcarnitine + 3-hydroxyisovalerylcarnitine (C4DC/C5OH). Urine analysis by gas chromatography-mass spectrometry showed persistently increased excretion of 3-OH-isovaleric acid. The combination of increased blood concentrations of C4DC/C5OH and increased urinary excretion of 3-OHisovaleric acid suggested a metabolic disorder associated with impaired biotin metabolism. Determination of the level of biotinidase in the blood did not reveal deviations from the reference values. Biotin was prescribed. As a result of clinical exome sequencing, complex heterozygous variants of the SLC5A6 gene encoding SMVT were identified. The patient was treated with increased doses of oral biotin, pantothenic acid, and lipoic acid, which resulted in significant clinical improvement.This study aims to explore the effectiveness of education and campaign approaches in building public awareness about the importance of preventing stunting in future generations.

The result showed that Bandung integrated green school has the whole-school approach to sustainability than non- green school. There are 20 programs implemented by Bandung green school by integrating them to the whole school community. Integrated green school initiative led the school to introduce sustainability through education.Measuring the level of acylcarnitines and free carnitine in the blood is one of the stages of early diagnosis of inborn errors of metabolism, including disorders of fatty acid oxidation, and ensures timely initiation of therapeutic measures. Currently, tandem mass spectrometry (MS/MS) is successfully used for these purposes. Dried blood spot acylcarnitine reference values developed for neonates are critical for interpreting test results and diagnosing fatty acid metabolic disorders. Objectives: To establish reference values for the concentrations of free carnitine and short-chain acylcarnitines in samples of dried blood spots of newborns in Western Kazakhstan using LC-MS/MS technology (liquid chromatography-tandem mass spectrometry). Methods: The cross-sectional study included 250 healthy newborns from Western Kazakhstan aged 1-3 days, born at term and breastfed, 49.2% boys and 50.2% girls. To establish age reference values for C0 and shortchain acylcarnitines, newborns were divided into three groups (1) 1-day, (2) 2-day and (3) 3-day. Guthrie blood samples were collected on days 1–3 of life and quantified using liquid chromatography-tandem mass spectrometry (LC-MS/MS). Nonparametric statistical approaches were used to obtain percentile distributions for newborns ranging from 2.5 to 97.5. Results: A statistically significant difference was found in the mean levels of acetylcarnitine (C2), butyrylcarnitine (C4) and tiglylcarnitine (C5:1) in men and women. The highest values were determined in the female group. Age-related differences were observed in the concentration levels of malonylcarnitine (C3DC), butyrylcarnitine (C4), isovalerylcarnitine (C5) and glutarylcarnitine (C5DC). No significant correlations were found between the content of C0 and 10 short-chain acetylcarnitines in dried blood spots and the body weight of newborns. Conclusion: The present study established concentrations of acylcarnitines and free carnitine that can be used as reference standards in a newborn screening program for inherited metabolic diseases in Kazakhstan.

Immunoglobulin Heavy Chain Gene Mutations in Chronic Lymphoid Leukemia

2024-08-31T23:33:02+03:00

Chronic lymphoid leukemia (CLL) is the most common type of leukemia in adults in western countries and is a clinically and genetically heterogeneous disease. Although the diseaseusually follows a slow course, significant survival differences are observed depending on clinical and biological factors. Some patients with CLL do not need treatment for many years, while others need urgent treatment. It is noteworthy that staging systems are inadequate in patient follow-up and predicting the course of the disease. Therefore, parameters that determine prognosis in CLL independent of disease stage have been developed. In recent years, mutation status of Immunoglobulin heavy chain variableregion(IgVH) genes has emerged as a strong marker for prognosis in CLL. Patients with CLL are divided into 2 subgroups with different clinical courses according to the mutation status in the IgVH genes: one refers to mutated IgVH segments with a more favorable clinical course and the other refers to non-mutated IgVH segments associated with a poor outcome. In this study, we will try to clarify the relationship between IgVH mutation status and CLL prognosis and survival.

Essential and Conditionally Essential Amino Acid Profile in West Kazakhstan Children with Suspected Inborn Errors of Metabolism

2024-08-31T23:43:26+03:00

Measuring the concentration of amino acids in the blood and compiling a metabolic profile of amino acids, taking into account the influence of factors such as age, gender, body weight, region of residence, is extremely important in the diagnosis of amino acid metabolic disorders, especially when conducting selective screening for inborn errors of metabolism (IEM). Aims: To describe the metabolic profile of essential and conditionally essential amino acids in samples of dried blood spots from children in Western Kazakhstan with suspected IEM using LC-MS/MS technology (liquid chromatography-tandem mass spectrometry). Methods: The cross-sectional study included 200 clinical-risk children of West Kazakhstan aged one day to 18 years, 52.5 % male and 47.5 % female. Depending on their age, the children were divided into the following groups: group A (newborns, age 1-30 days), group B (age 1 month -7 years) and group C (age 8-18 years). Blood samples on Guthrie cards were collected and quantified by LC-MS/MS. Nonparametric statistical approaches were used. The concentrations of arginine, glycine, leucine, isoleucine, hydroxyproline, methionine, phenylalanine, proline, tyrosine, valine in dried blood spots of children with suspected IEM were determined. Results: Significant differences were established between children with suspected IEM of different age groups in the concentrations of hydroxyproline, arginine, glycine, isoleucine, leucine, phenylalanine, proline, tyrosine and valine. A negative correlation with age for the majority of essential and conditionally essential Amino Acids indicates their decline with age in children with suspected hereditary metabolic diseases. Significant differences between groups of female and male children with suspected IEM were established only in the concentration of methionine in dried blood spots. The highest values were determined in female group. Conclusion: The results of this study may be important in conducting selective screening for IEM in various age groups of the pediatric population.

Determination of miRNA Expression Levels in Bladder Cancer

2024-08-31T23:47:23+03:00

Bladder cancer is the ninth most common cancer worldwide, with the highest incidence rates observed in men in some countries in Southern and Western Europe, North America, North Africa, or Western Asia (Antoni, S. et al., 2017). Although gender differences vary greatly between countries, incidence rates are lower in men than in women. According to the data announced by the World Health Organization in 2022: In European and Asian comparisons; This rate is 21.1% and 5.6% per 100,000 people, respectively, and 22.6% in Turkey (Globocan, 2022). MicroRNAs (miRNAs) are non-protein-coding, single-stranded RNA molecules of 18-25 nucleotides in length and constitute a class of endogenous small RNAs (Celik et al., 2013). Studies have shown that microRNAs may also function as oncogenes or tumor suppressors in Bladder cancer. Although the expression levels of microRNA 22 5p and microRNA 337 have been determined in many cancers, including lung, prostate and colon cancer, no studies have been found on their expression levels in bladder cancer patients. In our study, miRNA 22 5p and miRNA 337 5p expression levels in bladder cancer patients will be calculated quantitatively using the Real-Time PCR method. In the first stage of the study, samples will be taken from the bladder using the TUR method, one from healthy tissue and the other from cancerous tissue. miRNA will be isolated from the tissue samples taken, cDNA will be synthesized from the miRNA samples and expression levels will be determined with the Real-Time PCR method using miRNA 22 5p, miRNA 337 5p specific primers and U6 primer as the reference gene. The data will be analyzed and interpreted with the SPSS package program.This study was planned to determine whether these two miRNAs can guide early diagnosis and diagnosis in bladder cancer patients and to provide clinicians with diagnosis and treatment planning.

2024-09-05T21:39:14+03:00

Background: Venous congestion is an important complication in superficial temporal artery pedicled scalp flaps. In this study, we added deep temporal fascia, including the middle temporal vein, to the flap pedicle to prevent venous congestion in these flaps. Methods: A horn-shaped superficial temporal artery pedicled scalp flap was used to repair scalp and facial defects in 16 patients with a mean age of 52 years. The flaps were raised together with the superficial and deep temporal fascia at the base of the pedicle. The flap sizes ranged from 9 × 4 cm to 23 × 7 cm, and the mean follow-up period was seven months. Results: Venous congestion did not develop in any of the flaps. Abnormal hair distribution developed in three patients and hematoma in one patient. In all of the patients, the donor site was closed primarily and there was no flap loss. Conclusions: In scalp flaps with a superficial temporal artery pedicle, venous congestion can be prevented, and elevated more safely by adding a deep temporal fascia to the flap pedicle.
