Quantitative estimates of the effect of 7-hydroxymatairesinol (7-HMR) intake on estrogen balance and clinical aspects of the course of fibrocystic mastopathy have been carried out. Aim. Assessment of effects 7-HMR on metabolism of estrogen (16a-OHE1, 2-OHE2, 2-OHE1, 2-OMEE1, 4-OMEE2, 4-OHE1, a ratio 2-OHE1/16a-OHE1, 2-OHE1/2-OMeE1 and 4-OHE1/4-OMeE1) and progesterone in daily urine at patients with fibrous and cystous mastopathy in the post-menopausal period. Materials and methods. The analysis of metabolites of estrogen (16a-OHE1, 2-OHE2, 2-OHE1, 2-OMEE1, 4-OMEE2, 4-OHE1, ratios 2-OHE1/16a-OHE1, 2-OHE1/2-OMeE1 and 4-OHE1/4-OMeE1) and progesterone in daily urine with use of solid-phase immunofermental set (IFA) of Amerscham International on the analyzer of Amerkard by means of standard sets is carried out. Statistical 10.0 and Microsoft Excel spreadsheets were used in statistical material processing. Results. It was found that taking 7-HMR (60 mg/day, 1 month) contributes to normalizing estrogen metabolism (decreasing estradiol, estrone, estriol, 16a-OHE1) and improves the clinical symptoms of mastopathy. Conclusions. In patients with FCM, 7-HMR contributes to a decrease in hyperestrogenia-related tumor risks by lowering estrogen metabolites levels.

Background: Currently there is only one marker to objectively establish perimenopause ie menstrual irregularities. Due to the wide variation in hormones like LH, FSH, estradiol, they become unreliable in predicting approaching menopause. This study was conducted to study and compare the patterns of LH, FSH and Estradiol in normal and abnormal perimenopause using the Stages of Reproductive Ageing Workshop (STRAW) criteria.Methods: A comparative evaluation was done after enrolling 200 patients out of which 100 women were in normal perimenopause (early-25 and late perimenopause-75, depending upon menstrual characteristics as defined by STRAW criteria) and 100 having AUB. Sociodemographic data, presence of menopausal symptoms were recorded. S. LH, S.FSH and S. estradiol we determined by adapted solid phase direct sandwich ELISA.Results: FSH was in menopausal ranges (>20IU/L) in early and late perimenopause. LH and FSH in women with AUB ranged from pre to post menopausal ranges. There was significant difference in LH and FSH between normal perimenopause and abnormal uterine bleeding. Estradiol levels showed a significant difference between late perimenopause and AUB p=0.015.Conclusions: This study shows that there is a progressive incremental trend in FSH and LH and decremental trend in Estradiol from early to late perimenopause due to decrease in ovarian follicular reserve, although the difference is not significant. Clinical symptoms present in 50% of late perimenopausal women showed that besides menstrual characteristics we can correlate these menopausal symptoms with raised FSH and low Estradiol. These women can be picked up and preventive therapy may be provided.

The Relationship

In the last two decades, the treatment paradigms for Crohn’s disease and ulcerative colitis have significantly changed inclusive of a continuously increasing role of biological therapy (anti TNFs). Some patients, however, experience lack or loss of response to biological treatment, and in such cases the management of patients is often empirical. In this review, the authors aim to summarize the available data regarding epidemiology and predictors of loss of response to biological therapy considering the clinical factors and the relationship between serum concentrations, antibodies against biological agents, respectively. Monitoring drug levels and antibodies is expected to play an important role in the management of loss of response (i.e. to confirm adherence, allow dose adjustment, or provide rationale for switching to another biological agent or to a different class of biological agent) in the coming years. The optimal method of detection and cut-off values are, however, not clear. In clinical practice, meticulous complex assessment of clinical symptoms, confirmation of active disease by endoscopic or radiological imaging, and excluding complications remain necessary. Orv.

Personalized Approach

Biliary diseases are common, but clinical symptoms are often unspecific and direct access and visualization of the biliopancreatic system for diagnostic purpose is difficult. In the last decades endoscopic ultrasound (EUS) has become a primary method in the gastrointestinal tract. It significantly changed the role of endoscopy in diagnostic imaging in the gastrointestinal tract and adjacent organs. EUS has become an effective diagnostic tool in biliary stone disease as well as in the diagnosis of indeterminate biliary strictures. Furthermore, an EUS-directed transmural approach emerged as a safe and effective alternative to ERCP in patients requiring biliary drainage, in particular as a backup method if standard ERCP-approach fails. Development of new techniques, specific accessories and stents during the last decade led to an enormous step forward in terms of efficacy and safety of an EUS-directed approach. In the current article technical and clinical aspects of EUS-guided diagnostic and therapeutic approaches in different clinical indications will be discussed together with a review of the available data.

ABSTRACT The ovaries of ten patients, at least one year after the post-menopause, were incubated with two Δ5-C19-steroids and also studied histochemically. All these patients had post-menopausal uterine bleeding and increased oestrogen excretion of the urine. The urinary estimations of gonadotrophins, 17-KS, 17-OHCS and pregnanediol were carried out on all patients. Vaginal smears were read according to Papanicolaou, and the endometrium and ovaries were studied histologically. The incubation experiments indicate the presence of Δ5-3β-hydroxysteroid-dehydrogenase. When androst-5-ene-3β,17β-diol was used as precursor the formation of testosterone occurred without any concomitant production of DHA and/or androstenedione. This seems to indicate the possible role of the Δ5-pathway in the formation of testosterone by post-menopausal ovarian tissue. The histochemical reactions indicated a reducing activity on NADH, lactate and glucose-6-phosphate, in certain corpora albicantia, atretic follicles and in diffuse thecoma regions in the cortical layer of the ovary. Steroid-3β-ol-dehydrogenase and β-hydroxybutyrate-dehydrogenase were found only at the edges of certain corpora albicantia, in some individual stroma cell groups and in some atretic follicles. Our studies, both biochemical and histochemical, suggest that the observed increase in the urinary oestrogens of the patients studied might in part at least, be of ovarian origin. This opinion is also supported by the postoperative oestrogen values.

Potential Role of Cytokines in Children with Acute Appendicitis and Acute Mesenteric Lymphadenitis Although, AAP and AML have different etiological factors, clinical symptoms are very much similar but treatment tactics in both the disease differ a lot. In case of AML, treatment is more conservative and does not require hospitalization while in case of AAP immediate hospitalization and maybe further surgery can be mandatory. With the identification of group of cytokines serum inflammatory mediators IL-8, IL-10, IL-12[p70], IL-17, TNF-a and MCP-1, it is believed early and proper diagnosis of AAP in the near future. Research of cytokines-serum inflammatory mediators has opened new opportunities for an early detection and differentiation of these two diseases in children.

The World

On 11th March 2020, the World Health Organisation (WHO) announced a pandemic caused by a novel beta-coronavirus SARS-CoV-2, designated COVID-19. The virus emerged in December 2019 in Wuhan, China, has spread across the world as a global pandemic. The traditional use of medicines from plants can be traced back to 60,000 years. Global interest in the development of drugs from natural products has increased greatly during the last few decades. Essential oils (EOs) have been studied through the centuries and are known to possess various pharmaceutical properties. In the present review, we have highlighted the current biology, epidemiology, various clinical aspects, different diagnostic techniques, clinical symptoms, and management of COVID-19. An overview of the antiviral action of EOs, along with their proposed mechanism of action and in silico studies conducted, is described. The reported studies of EOs' antiviral activity highlight the baseline data about the additive and/or synergistic effects among primary or secondary phytoconstituents found in individual oils, combinations or blends of oils and between EOs and antiviral drugs. It is hoped that further research will provide better insights into EOs' potential to limit viral infection and aid in providing solutions through natural, therapeutically active agents.

The Impact

Geomicrobiology, the marriage of geology and microbiology, is about the impact of microbes on Earth materials in terrestrial systems and sediments. Many geomicrobiological processes occur over long timescales. Even the slow growth and low activity of microbes, however, have big effects when added up over millennia. After reviewing the basics of bacteria–surface interactions, the chapter moves on to discussing biomineralization, which is the microbially mediated formation of solid minerals from soluble ions. The role of microbes can vary from merely providing passive surfaces for mineral formation, to active control of the entire precipitation process. The formation of carbonate-containing minerals by coccolithophorids and other marine organisms is especially important because of the role of these minerals in the carbon cycle. Iron minerals can be formed by chemolithoautotrophic bacteria, which gain a small amount of energy from iron oxidation. Similarly, manganese-rich minerals are formed during manganese oxidation, although how this reaction benefits microbes is unclear. These minerals and others give geologists and geomicrobiologists clues about early life on Earth. In addition to forming minerals, microbes help to dissolve them, a process called weathering. Microbes contribute to weathering and mineral dissolution through several mechanisms: production of protons (acidity) or hydroxides that dissolve minerals; production of ligands that chelate metals in minerals thereby breaking up the solid phase; and direct reduction of mineral-bound metals to more soluble forms. The chapter ends with some comments about the role of microbes in degrading oil and other fossil fuels.

The dimple occurs by sudden pressure inversion at the droplet’s bottom interface when a droplet collides with the same liquid-phase or different solid-phase. The air film entrapped inside the dimple is a critical factor affecting the sequential dynamics after coalescence and causing defects like the pinhole. Meanwhile, in the coalescence dynamics of an electrified droplet, the droplet’s bottom interfaces change to a conical shape, and droplet contact the substrate directly without dimple formation. In this work, the mechanism for the dimple’s suppression (interfacial change to conical shape) was studied investigating the effect of electric pressure. The electric stress acting on a droplet interface shows the nonlinear electric pressure adding to the uniform droplet pressure. This electric stress locally deforms the droplet’s bottom interface to a conical shape and consequentially enables it to overcome the air pressure beneath the droplet. The electric pressure, calculated from numerical tracking for interface and electrostatic simulation, was at least 108 times bigger than the air pressure at the center of the coalescence. This work helps toward understanding the effect of electric stress on droplet coalescence and in the optimization of conditions in solution-based techniques like printing and coating.

Caspase-14 is a unique member of the caspase family—a family of molecules participating in apoptosis. However, it does not affect this process but regulates another form of programmed cell death—cornification, which is characteristic of the epidermis. Therefore, it plays a crucial role in the formation of the skin barrier. The cell death cycle has been a subject of interest for researchers for decades, so a lot of research has been done to expand the understanding of caspase-14, its role in cell homeostasis and processes affecting its expression and activation. Conversely, it is also an interesting target for clinical researchers searching for its role in the physiology of healthy individuals and its pathophysiology in particular diseases. A summary was done in 2008 by Denecker et al., concentrating mostly on the biotechnological aspects of the molecule and its physiological role. However, a lot of new data have been reported, and some more practical and clinical research has been conducted since then. The majority of studies tackled the issue of clinical data presenting the role of caspase in the etiopathology of many diseases such as retinal dysfunctions, multiple malignancies, and skin conditions. This review summarizes the available knowledge on the molecular and, more interestingly, the clinical aspects of caspase-14. It also presents how theoretical science may pave the way for medical research. Methods: The authors analyzed publications available on PubMed until 21 March 2021, using the search term “caspase 14”.
