Background: The influence of Helicobacter pylori (HP) in inflammatory disorders of the digestive mucosa has been the subject of several studies since socioeconomic, personal and environmental factors were implicated in the bacteria transmission.
Aim: To correlate the inflammatory endoscopic findings with HP infection and the onset of mucosal diseases mucous of the upper digestive tract.
Method: Comparative observational study, in which were collected data from 2247 patients who underwent upper endoscopy and biopsies for HP with urease test. The patients were divided into two groups: HP+ and HP- (control) in which endoscopic findings were observed for the following changes: esophagitis, esophageal ulcer, gastritis, erosive gastritis, gastric ulcer, bulboduodenitis, bulbar ulcer and without disease.
Results: As for esophagitis, there was little disparity in the distribution favorable to HP+ group (HP+ =67.11% and HP- =69.89%) and esophageal ulcer (HP+ =0% and HP- =0, 21%). Gastritis was favorable to HP- group (HP+ =78.34% and HP- =73.63%), as well as erosive gastritis (HP+ = 67,11% and HP- = 64,55%), in bulboduodenitis (HP+ =1,87% and HP- 1,23%), in gastric ulcer (HP+ =2,14% and HP- =2,03%) and in the absence of alterations in the HP+ group (4.81%) with the HP- control group (6,30%), in which there was little disproportion in favor of HP- group, but without statistical significance. As for the bulbar ulcer (HP +=10.16% and HP- =4.48%), there was statistically significant (p=0.00001).
Conclusion: There is no difference between HP+ and HP- groups in inflammatory changes in endoscopic gastroduodenal mucosa, except for the relationship between HP and bulbar ulcer.

This study investigated the relationship between stepping-defined daily activity levels, time spent in different postures, and the patterns and intensities of stepping behaviour. Using a thigh-mounted triaxial accelerometer, physical activity data from 3547 participants with seven days of valid data were analysed. We classified days based on step count and quantified posture and stepping behaviour, distinguishing between indoor, community, and recreation stepping.

The effect of 2-hydroxpropyl-β-cyclodextrin (2HPβCD) with or without divalent metal ions (Ca, Mg, and Zn) on the stability of dalbavancin in acetate buffer was investigated. Dalbavancin recovery from formulations with 2HPβCD and divalent metal ions after four weeks of storage at 5 °C and 55 °C was measured by RP-HPLC and HP-SEC; a longer-term study was carried out over six months at 5 °C, 25 °C, and 40 °C. Binding of 2HPβCD was characterized by isothermal titration calorimetry (ITC) and nuclear magnetic resonance (NMR).

Nabumetone (NAB) is a poorly soluble nonsteroidal anti-inflammatory prodrug (BCS class II drug) whose solubility is significantly improved by complexation with cyclodextrins (CDs). : The solid complexes, in a 1:1 molar ratio, were prepared by mechanochemical activation by grinding, using β-cyclodextrin (β-CD) and its derivatives, hydroxypropyl- and sulfobutylether-β-cyclodextrin (HP-β-CD and SBE-β-CD). The complexation was confirmed by differential scanning calorimetry (DSC), powder X-ray diffraction (PXRD), and attenuated total reflectance Fourier-transformed infrared spectroscopy (ATR-FTIR).

: This study evaluated how the relative proportion of chitosan (CS) to the polyanions alginate (ALG) and hydroxypropyl-methylcellulose phthalate (HP) affects the colloidal properties of mesalazine (MSZ) nanosuspensions as a strategy to produce particles with specific characteristics. : Nanosuspensions were prepared using a bottom-up approach based on acid-base reactions and were modified with CS in a binary mixture with ALG or a ternary mixture with ALG and HP. The particle size, polydispersity index (PDI), zeta potential, morphology, and drug association efficiency were analyzed.

Many indigenous plants of the Philippines, including essential oil-bearing species, remain phytochemically and pharmacologically unexplored. In this study, the chemical composition of leaf essential oils (EOs) hydrodistilled from (Lauraceae) and (Piperaceae) was determined using dual-column (HP-5MS/DB-WAX)/dual-detector gas chromatography and mass spectrometry analysis. Caryophyllene oxide (15.
