Obesity is a multifactorial epidemic disease of environmental origin that affects subjects of all countries and whose origin is not in the stomach or intestines. Surgical treatment represents a unique case of surgery for operating healthy organs, which are not the cause of the disease and do not improve after the operation. Kremen and Linner [1] and Varco and Buchwald teams of in Minneapolis, MN began the intestinal deviation (ID) of malabsorption in 1954. Payne [2] and Scott [3] developed these ID techniques in the 1960s leaving only 14- 4 inches (35 -10 cm) as an absorption zone and were abandoned in the 1970s due to its serious metabolic (malnutrition) and liver complications (liver failure).

The case is that of 83 year-old African American man with hypertension, hepatitis C induced decompensated cirrhosis with ascites, end-stage renal disease (ESRD) on hemodialysis, fluid overload with peripheral edema and chronic hypotension. The patient was referred to the dialysis access center of Pittsburgh, PA for evaluation of his prolonged bleeding from the left upper arm brachial-basilic arterial-venous fistula (BBAVF).

Delivering health care is a complex task that marginalized a portion of the population intentionally or unintentionally. Discrepancy in health care providing to the intended patients is sometimes accompanied by unintended collateral damage to the bystanders who desperately needing our help and assistance.

This review aims to emphasize the scientific focus on platelet therapies by presenting the results already obtained in mares susceptible to Persistent Breeding-Induced Endometritis (PBIE), as well as highlighting opportunities for further improvement. The recent publication demonstrating the absence of bacterial growth in susceptible mares treated with PRP underscores the potential of regenerative therapies to control infections without promoting the emergence of multidrug-resistant bacteria. Alternative therapies have gained prominence in the current public health context, with the World Health Organization listing antimicrobial resistance among the ten most significant global threats. Endometritis is the leading cause of subfertility in mares, and empirical antibiotic therapies are commonly used in the field due to market pressures related to the high financial value of embryos, along with logistical challenges in obtaining laboratory-dependent diagnostic results. Platelet-Rich Plasma (PRP) is an alternative therapy derived from whole blood plasma with a high concentration of platelets. Its anti-inflammatory, regenerative, and antimicrobial properties are particularly tested when traditional therapies fail to achieve the desired effect. In recent years, research on the use of PRP in equine reproduction has primarily focused on endometritis, with a particular emphasis on persistent breeding-induced endometritis (PBIE). However, there is a growing interest in other platelet derivatives, such as lyophilized platelet-rich plasma and platelet lysate, which offer practical field applications.

In the actual medical therapy of BPH, we can see: antibiotics, alpha blockers, 5-ARI, fitotherapeutics/natural products (Serenoa repens) with different which display clinical activities and other molecules such as FANS (local or systemic dosage forms) cortisones and others. Relationship between immune systems and chronic prostatitis are strictly involved in BPH progression. A vicious cycle that involve chronic flogosis, tissue remodeling, grow factors, inhibition of apoptosis, and other phenomena. Observing BPH pathogenesis under an immunologic point of view make possible to search new pharmacological strategies, to improve actual therapy. The aim of this work is to observe some relevant literature in our opinion related the management of BHP and its progression under a pharmaceutical and immunological point of view. A deep knowledge in the pharmaceutical properties of some molecules (antimicrobials, anti-phlogosis agents, Anti-androgenic agents, alpha blockers, 5-ARI and other treatments, techniques, interventions or instruments) can help the physicians to pick the right choice.

Background & Objectives: Fluoride releasing bonding agents can help the orthodontist to minimize enamel demineralization independent of patient cooperation. This in vivo study was conducted to evaluate the efficacy of resin modified glass ionomer cement (RMGIC) on reducing enamel demineralization around orthodontic brackets and confirm the superior caries-preventive effect of RMGIC by assessing the mutans streptococci (S. mutans) in plaque samples in vitro. Methods: 60 subjects (aged 14-20 years) scheduled to have premolar extractions as part of the orthodontic treatment plan were selected and randomly divided into 2 groups of 30 each (group 1: the brackets were bonded on the teeth using light cure composite resin and group 2: the brackets were bonded using RMGIC). Plaque scores (modification of plaque index by Silness and Loe) were recorded and plaque samples were collected before bonding, one week and one month after bonding. S.mutans colonies were recorded from the plaque samples inoculated on MSB agar plates, incubated under 95% N2 and 5% CO2 for 48 hours at 370C in a CO2 jar. After 1 month, the right maxillary and mandibular first premolars were debonded, extracted and depth of enamel demineralization area was estimated using polarized light microscope. Results: After statistical analysis, a significantly higher mean depth of demineralized lesions was noticed in group 1 as compared to group 2. A significant difference between occlusal and gingival depth was seen only in group 2, thus illustrating a wedge effect. In group 1, a statistically significant increase in the mean colony forming units (CFU) of S.mutans has been noticed at different time intervals whereas in group2, a significant increase was observed only at 1month. Unlike at 1 month, a statistically significant difference in mean CFU between group 1 and group 2 has been observed at 1 week (P<0.05). Conclusions: Enamel lesions adjacent to the bracket base on teeth bonded with the RMGIC were smaller than those on teeth bonded with a composite resin. The high “burst effect” of fluoride release for the first few days of RMGIC after bonding is confirmed by statistically significant reduction in CFU counts of S. mutans in plaque.

Mester et al., stated the laser effects in a review of their studies of 15 various biological systems, they observed the stimulating effect of low energy (in terms of J/cm2) laser and inhibiting effect of high energy laser and later reported the relationship of cumulative energy applied and the effects conforms to the Arndt-Schultz law. They concluded their experience with 875 healed cases and the results of their experiments had convinced them to recommend the use of lasers to stimulate wound healing [1].

Salivary stone (sialothiasis) is a calcifying concentration within the ductal system of salivary gland [1]. The majority of salivary calculi occur in the submandibular gland duct because of its length, upward course and the thicker mucus [2].

In our past 200 years we have seen the advancing development of Dental Arts and Science though discoveries by its practitioners. Perhaps it will do some good to review the basis upon which fixed tooth replacement has evolved—that is the prosthetic crown.

Mast cells play a central role in the genesis and modulation of allergic and inflammatory responses. The general aim of the present work was to study the interaction between mast cells and the most common additives approved for use in foods. Dose-response studies about the effect of the main food additives (tartrazine, sodium bisulphite and sodium benzoate) on mast cell degranulation were carried out. Rat peritoneal mast cells were incubated with: 1) buffer solution or 2) stimulus. The stimuli were tartrazine, sodium benzoate, sodium bisulphite and the calcium ionophore A23187. A23187 was used as a reference mast cell secretagogue. Different doses and combinations of food additives were used. The viability of the mast cells was evaluated with trypan blue. In the incubation solutions, the release of β-hexosaminidase was quantified by colorimetric reaction and ELISA plate reader. The remaining β-hexosaminidase concentration (not released) was studied in the cells after the incubations, and morphology of the mast cells was analyzed by light microscopy with toluidine blue stain. The food additives tartrazine, sodium benzoate and sodium bisulphite did not stimulate the release of β-hexosaminidase from mast cells at any of the concentrations used. In contrast, tartrazine at concentrations of 0.1 μM and 1 μM, and sodium benzoate and sodium bisulphite at concentrations of 0.1 μM, 1 μM, 10 μM and 100 μM, significantly inhibited the basal release of β-hexosaminidase from mast cells. Considering these findings, we decided to determine the effect of these additives on the degranulation of mast cells induced by the calcium ionophore A23187. Sodium bisulphite inhibited mast cell activation induced by the calcium ionophore A23187 in this experimental model. The present study demonstrates that food additives of usual permitted use do not stimulate basal degranulation of mast cells in an in vitro model of peritoneal mast cells and that the additive sodium bisulphite inhibit mast cell activation induced by intracellular calcium increase. This food additive could represent an interesting alternative in the prevention of pathologies mediated by mast cells, as well as in the field of nutritional biochemistry.
