Rheological properties of lactose-free dairy desserts

People suffering from lactose intolerance cannot digest milk or lactose-containing foods. Lactose-free diet is essential for them since they do not have the ability to produce lactase to breakdown milk sugar. Physical properties of lactose-free dairy desserts will most probably be different than that of lactose containing ones because of lactose hydrolysis. In this study, it was aimed to analyze the rheological and textural behaviors of different lactose-free dessert formulations containing different gum types and different waxy maize starch and sucrose concentrations. Waxy maize starch was used at concentrations of 0.032 g·mL^-1, 0.040 g·mL^-1, and 0.048 g·mL^-1 In addition to waxy maize starch, guar gum, gum arabic, or κ-carrageenan at two different concentrations (1.0% w/w and 0.5% w/w) was added. Sucrose was added at concentrations of 0.14 g·mL^-1 and 0.10 g·mL^-1 in lactose-free desserts. Power law model was found to be suitable to explain the flow behavior of desserts. The storage and loss modulus of lactose-free desserts were higher than that of lactose-containing desserts. The κ-Carrageenan was found to be the most effective gum for structure build-up.

A THANATOPHORIC DYSPLASIA TYPE I CASE WITH A FGFR3 P.R248C MUTATION AND SURVIVAL BEYOND THE NEONATAL PERIOD

A Thanatophoric dysplasia, is a severe congenital anomaly which mostly causes stillbirth or death of the affected baby within hours due to respiratory insufficiency. The diagnosis of TD is typically suspected on ultrasound during the second trimester of pregnancy, when severe shortening of the long bones, frontal bossing, flattened vertebrae, and short ribs that result in a narrow thorax and bell-shaped abdomen, can be seen. Here, we present a case with prenatal ultrasonographic findings suggestive of TD, and highlight the patient's postnatal dysmorphic features and typical radiographic findings. The definitive diagnosis of TD type I (TDI) was made postnatally, when molecular genetic analysis revealed the previously described p.R248C mutation in FGFR3. This case is reported due to its relative long life span and the definitive molecular diagnosis that could be made during hospitalization.

Evaluation of frequency of nausea and vomiting as well as depression level in pregnant women

OBJECTIVE

To determine the frequency of nausea and vomiting in pregnant (NVP) women, review associated factors, and evaluate the depression level.

MATERIALS AND METHODS

The study is a cross-sectional research conducted in pregnant women who applied to Sakarya Training and Research Hospital and Sakarya Maternity and Children Hospital between January 13, 2013 and March 23, 2013. The study group consisted of 606 pregnant women who were below 20 weeks gestation and agreed to take part in the study. The questionnaire form prepared in line with the study objective was completed by the pregnant women under supervision. The women who had a complaint of nausea and vomiting at least once a day during their pregnancy were deemed as "having a history of nausea and vomiting". Rhodes index was used to evaluate the severity of nausea and vomiting. Depression level was evaluated with the Beck Depression Inventory. Chi-square test and Spearman's Correlation Analysis were used to analyze the data. Statistical significance value was accepted as p < 0.05.

RESULTS

The age of pregnant women in the study group ranged from 17 to 39 years (mean age: 25.55 ± 4.95). The frequency of having nausea and vomiting in the pregnant women was determined to be 35.1% (n = 213). The frequency of having nausea and vomiting was determined to be higher in those with a nuclear family, working women, those with a poor family income, those who used any contraception method before the pregnancy, and those who had a history of nausea and vomiting in their previous pregnancy(ies) (p < 0.05 for each). The pregnant women with a history of nausea and vomiting reported that their complaints increased the most with the smell of food as well as perfume/cigarette/body odor. In the women with a history of nausea and vomiting, frequency of depression was significantly higher (p < 0.05). A positive relationship was found between the severity of nausea and vomiting and depression level (p < 0.05).

CONCLUSIONS

Nausea and vomiting were determined to be a major health problem in pregnancy. Depression frequency was higher in those with a history of nausea and history. The severity of nausea and vomiting increased with higher depression levels. More detailed studies are required to determine the causes of NVP as well as the risk factors.

Preparation of human resources for future nuclear energy using FBNR as the instrument of learning

An increasing number of developing countries are showing interest to become the emerging countries to nuclear energy. Most of these countries lack human resources and adequate infrastructures to enter such a venture. The principle objective of activities of FBNR Group is to train human resources for the countries that at the present lack the necessary conditions, but aim at the future clean and safe nuclear energy through the fourth generation and INPRO compatible nuclear reactors. The preparation for the future nuclear energy is done through development of innovative nuclear reactor that meets the INPRO philosophies and criteria. These countries may or may not have decided as yet to utilize nuclear energy, but are interested to gain a strong educational foundation for their future. The research and development of a small innovative nuclear reactor FBNR is used as the instrument for learning. The young scientists will learn how to be innovative with the vision of INPRO philosophy and criteria.

Acupuncture relieves symptoms in chronic prostatitis/chronic pelvic pain syndrome: a randomized, sham-controlled trial

BACKGROUND

There are multiple approaches to the management of chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS); and lately the data suggesting the ability of acupuncture treatment to decrease pain, positively impact quality of life and potentially modulate inflammation has suggested it as a potential therapeutic option for men with CP/CPPS. We conducted this study to determine whether acupuncture is really an effective therapeutic modality for CP/CPPS in terms of >50% decrease in total National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) score from baseline compared with sham.

METHODS

One hundred patients with CP/CPPS (category III B) in an outpatient urology clinic were randomized to receive acupuncture at either seven acupoints bilaterally or sham points adjacent to these points. NIH-CPSI was completed by each patient before and 6, 8, 16, 24 weeks after the treatment. Mean values of total CPSI score and subscores after the treatment and on follow-up following the treatment were compared.

RESULTS

Of the acupuncture participants, 92% were NIH-CPSI responders (>50% decrease in total NIH-CPSI score from baseline) compared with 48% of sham participants, 8 weeks after the end of the therapy. Both groups experienced significant decrease in CPSI subscores throughout the whole follow-up period; however, the decline remained significantly greater in the active acupuncture group as compared with the sham group.

CONCLUSIONS

Our results show that the use of acupuncture in treatment of men with CP/CPPS symptoms resulted in a significant decrease in total NIH-CPSI scores.

Traditional risk factors and angiotensin-converting enzyme insertion/deletion gene polymorphism in coronary artery disease

We investigated whether the insertion/deletion (I/D) polymorphism in the angiotensin-converting enzyme (ACE) gene and serum ACE levels are associated with traditional risk factors of coronary artery disease (CAD). We enrolled 250 individuals without CAD and 750 individuals suffering from CAD who were angiographically diagnosed. Biochemical risk factors, the ACE (I/D) gene polymorphism, and ACE serum levels were compared. ACE genotypes were determined using real-time polymerase chain reaction. ACE serum levels were determined using an enzyme-linked immunosorbent assay. Lipid parameters were determined spectrophotometrically using an autoanalyzer. Compared to the control group, the CAD group showed significantly higher serum ACE levels (P < 0.001). The highest ACE levels were found in those with the DD genotype. Other genotypes also presented statistically significant differences. We observed a significant difference between the control and coronary patient groups regarding the levels of total cholesterol, triglyceride, high-density lipoprotein-cholesterol, and low-density lipoprotein-cholesterol (P < 0.05). ACE (I/D) genotypes and serum ACE levels may be associated with risk factors and the development of CAD.

Oncologic results, functional outcomes, and complication rates of transperitoneal robotic assisted radical prostatectomy: single centre's experience

BACKGROUND

We report the operative details and short term oncologic and functional outcome of the first 334 Robotic-assisted radical prostatectomy experiences for organ confined prostate cancer

METHODS

From August 2009 to December 2012, details of 334 consecutive patients were retrospectively analyzed. The analyzed parameters included: preoperative, per-operative characteristics, postoperative minor and major complications, positive surgical margin continence, potency, and biochemical progression at the follow-up period.

RESULTS

The classical extrafascial, interfascial, intrafascial and fascia sparing radical prostatectomy were performed in 31, 41, 200, and 62 cases, respectively. The mean operation time was 213.8±90.1minutes, and the mean estimated blood loss was 116.1±58.9cc during operation. A nerve-sparing procedure was performed bilaterally in 198 (59.3%) cases and unilaterally in 126 (37.7%) cases. The catheter was removed on postoperative day 9, 1±1.9. Surgical margin was positive in 36 (10.7%) patients. The overall, pT2, pT3a and pT3b PSM rates were 8 (2.4%), 12 (3.6%), 16 (4.8%) respectively and PSM and BCR rates were not statistically different among four approach (P>.05). At the follow-up period, the continence rates were 74.4%, 80.4%, 80.5%, and 96.7% (P<.001), and previously potent patients' potency rates were 64.3%, 66.6%, 68.1%, and 74.5% (P>.05), in classic extrafascial, interfascial, intrafascial, and fascia sparing intrafascial prostatectomy, respectively.

CONCLUSION

RARP is a safe and feasible technique in treatment of localized prostate cancer. Fascia sparing approach has better continence rate. This results need to be supported by new prospective, randomized studies.

Evaluation of whether the ACE gene I/D polymorphism constitutes a risk factor for chronic obstructive pulmonary disease in the Turkish population

Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow obstruction that occurs as a result of the normal inflammatory process to protect against harmful irritants and chemicals. Another physiological regulatory process, the renin angiotensin system (RAS), plays an important role in the pathology of many diseases. Angiotensin converting enzyme (ACE) is a key enzyme of RAS. We investigated the frequency of the ACE gene I/D polymorphism in patients with COPD in Turkey. This study was performed on 47 unrelated patients with COPD and 64 healthy subjects. DNA samples were isolated from peripheral blood, and ACE DNA was amplified by polymerase chain reaction. The frequencies of ACE genotypes were 27.7, 55.3, and 17% for DD, ID, and II in the COPD group, respectively, and 43.8, 43.8, and 12.4% in the control group. There was no statistically significant difference between groups (X(2) = 3.078; df = 2; P = 0.220). The distributions of ACE gene D alleles were 38.2% (N = 52) in the COPD group and 61.8% (N = 84) in the control group; and those of I alleles were 48.8% (N = 42) in the COPD group and 51.2% (N = 44) in the control group. There was no statistically significant difference between groups for allele frequency (X(2) = 2.419; df = 2; P = 0.120). We believe these results can be useful for large-scale population genetic research considering the frequency of the ACE gene variation in COPD patients in the Turkish population.

Intrinsic factors rather than vitamin D deficiency are related to insulin resistance in lean women with polycystic ovary syndrome

OBJECTIVE

To investigate the correlation between insulin resistance (IR) and serum 25-OH-Vit D concentrations and hormonal parameters in lean women with polycystic ovary syndrome (PCOS).

PATIENTS AND METHODS

50 lean women with PCOS and 40 body mass index (BMI) matched controls were compared in terms of fasting insulin and glucose, homeostatic model assessment insulin resistance (HOMA-IR), 25-OH-Vit D, high sensitivity C-reactive protein (hs-CRP), luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone, dehydroepiandrosterone sulfate (DHEA-S), total cholesterol, high density lipoprotein (HDL), low density lipoprotein (LDL), triglycerides and Ferriman-Gallway (FG) scores. Correlation analyses were performed between HOMA-IR and metabolic and endocrine parameters.

RESULTS

30% of patients with PCOS demonstrated IR. Levels of 25-OH-Vit D, hsCRP, cholesterol, HDL, LDL, triglyceride and fasting glucose did not differ between the study and control groups. Fasting insulin, HOMA-IR, LH, total testosterone, and DHEA-S levels were higher in PCOS group. HOMA-IR was found to correlate with hs-CRP and total testosterone but not with 25-OH-Vit D levels in lean patients with PCOS.

CONCLUSIONS

An association between 25-OH-Vit D levels and IR is not evident in lean women with PCOS. hs-CRP levels do not indicate to an increased risk of cardiovascular disease in this population of patients. Because a strong association between hyperinsulinemia and hyperandrogenism exists in lean women with PCOS, it is advisable for this population of patients to be screened for metabolic disturbances, especially in whom chronic anovulation and hyperandrogenism are observed together.
