Current knowledge about the effect of alcoholic beverages on postprandial functioning of the digestive system is scarce and inconsistent. This study addresses their influence upon meal movement along the gut and meal-induced gallbladder emptying.

Purpose: This pilot study aims to explore how skin parameters and body composition impact the tolerance to EMS (Electrical Muscle Stimulation) stimuli in women, particularly focusing on pain tolerance in response to varying intensities of EMS. This research seeks to understand what is essential for optimizing EMS applications. Patients and Methods: The study involved 16 females (age 35.9 ± 12.3). Body composition and anthropometric measurements were taken, including BMI (Body Mass Index), weight percentage, WHtR (Waist to Height Ratio), WHR (Waist-Hip Ratio), and Bioelectrical Impedance Analysis. High-frequency ultrasound scans were conducted to assess skin parameters. The EMS stimulation was performed using an Evolvex (InMode, Israel), with applicators placed around the abdomen and intensity adjusted according to patient tolerance, recorded at the pain threshold. Results: The maximum tolerated EMS stimulus varied from 12V to 55V, with a median of 33V. Body weight showed a strong positive correlation (R=0.76, p< 0.001) and hip circumference (R=0.66, p< 0.001) with EMS intensity. Body fat mass (R=0.61, p=0.012) and visceral fat area (R=0.55, p=0.029) were positively correlated with EMS intensity. However, no significant correlations were observed between EMS tolerance and muscle tissue parameters or total body water content. The study also found that skin structure parameters showed no significant impact on EMS tolerance. Conclusion: The study reveals that women’s tolerance to EMS stimuli is influenced by various factors. Anthropometric parameters like hip circumference, body weight, skinfold, and BMI are strongly correlated with EMS tolerance. Body composition factors, particularly adipose tissue characteristics such as body fat mass and percentage, also significantly impact EMS intensity requirements, with no notable correlation to muscle tissue or water content. However, variations in skin structure, including thickness and density, do not significantly affect EMS tolerance. These insights are crucial for tailoring personalized EMS therapy to enhance effectiveness and comfort in both aesthetic and rehabilitative applications.

The present study was aimed to improve and simplify the ¹³C-mixed TAG (¹³C-MTG) breath test while keeping it acceptable for the patient. Healthy volunteers (ten women and eight men) were examined on four occasions, receiving in a random order 300 mg ¹³C-MTG: (1) contained in two wafers; (2) administered with a 50 g wheat roll; as well as given with either (3) 10 or (4) 30 g butter, spread onto a 50 g wheat roll, as the test meal, respectively. Samples of expiratory air were taken for 6 h postprandially for the mass spectroscopic measurement of ¹³CO₂ enrichment. After intake of the sole ¹³C-MTG, the cumulative ¹³C recovery in breath air (AUC) appeared to be unsatisfactory, as after 6 h it did not exceed 10 %. Application of the substrate with the 50 g wheat roll did not bring about any improvement in this parameter. The addition of the unlabelled fat to the test meal dramatically increased the cumulative ¹³C recovery. However, we found higher values for the momentary ¹³C recovery and AUC with 10 g butter compared with 30 g. It can be concluded that: (1) addition of unlabelled fat is indispensable to obtain a proper course of the breath ¹³C elimination during the conduct of the ¹³C-MTG breath test and (2) it is possible to apply a considerably smaller amount of the unlabelled fat than has previously been recommended for this test.

Sesame oil has been widely used for centuries. It is not only used as a kitchen ingredient, but it is also used to apply to the skin. Sesame oil contains natural compounds such as sesamol, sesamolin and sesamide, which have the ability to reflect or absorb certain UV rays. These substances can act as UV filters, helping to minimize the effects of harmful UV radiation on the skin. The aim of the study was to investigate the radioprotective/sun protection properties of sesame oil. The influence of sesame oils from different manufacturers on the directional reflectance of the skin was analyzed at various time intervals. To assess the sunscreen properties of the oil, a new technique was used: the 410-Solar hemispherical directional reflectometer. Sesame oil can be used in sunscreen preparations, but only when combined with other, more powerful ingredients. The oil itself is not sufficient protection against solar radiation. The study revealed no significant disparities in performance between the tested sesame oils from diverse manufacturers.

We evaluated the reproducibility of the ¹³C-phenylalanine breath test (¹³C-PheBT). On three separate days, 21 healthy volunteers (11 F and 10 M) underwent ¹³C-PheBT with 100 mg l-[1-¹³C]phenylalanine taken orally. Short-term reproducibility was evaluated with paired examinations taken 3 days apart; paired examinations separated by 23 days (median) served for the medium-term reproducibility assessment. Expiratory air was sampled at 19 points throughout 3 h. Determined limited reproducibility of the ¹³C-PheBT must be taken into consideration while interpreting the results of this diagnostic tool. The results of this study imply the following conclusions: (i) From among the three parameters examined, the cumulative ¹³C recovery area under the curve (AUC) offers much better reproducibility than the maximum momentary ¹³C recovery in the expiratory air (D_max) or the time to reach the maximum momentary ¹³C recovery (T_max) (ii) Collection of the breath air samples for 2 h results in a much better reproducibility of AUC, than for 1 h only; (iii) Reproducibility of ¹³C-PheBT is affected neither by the duration of the time gap between repeated tests nor by gender; (iv) Comparison with data obtained formerly reveals that reproducibility of the ¹³C-PheBT is worse than either that of of the ¹³C-methacetin (¹³C-MBT) or the ¹³C-alpha-ketoisocaproic acic (¹³C-KICA-BT) breath tests. This finding will have to be taken into consideration while interpreting the results of this diagnostic tool.

Diamond microdermabrasion is one of the most popular cosmetological treatments in the field of mechanical, controlled abrasion of the stratum corneum corneocytes. In this study, the influence of micropeeling on the optical properties of the skin features was investigated. The directional reflectance of the skin was measured before and after the procedure. The study involved 15 women aged 23–26. The tests were performed on the surface of the skin in 15 spots—on the forearms, arms and lower legs. Post-treatment reflectance increased significantly in the wavelength range of 700–2500 nm. In the remaining ranges it also increased, except for the range 480–600 nm, in which it decreased, but insignificantly. It was found that the optical properties of the skin after microdermabrasion changed, the directional reflectance of the skin increased, especially in the infrared range. The main conclusion from the conducted research is that the directional-hemispherical reflectance method can be used to identify female skin features in response of microdermabrasion treatment.
