Growth kinetics of Lactococcus lactis and Lactobacillus casei in liquid culture medium containing as prebiotics inulin or fructose.

Background: Predictive microbiology is a tool that allows us to evaluate the behavior of the concentration of biomass and estimated cells under extrinsic conditions, providing scientific and industrial benefits. In the present study, the growth of L. lactis and L.

Effect of Atomized Black Maca ( Supplementation in the Cryopreservation of Alpaca ( Epididymal Spermatozoa.

Artificial insemination is an important assisted reproductive technology that has been applied in several mammalian species. However, successful cryopreservation of semen of South American camelids has been limited, hindering the commercial application of artificial insemination in alpaca species. In this scenario, the addition of antioxidants to semen extenders provides a strategy to improve the freezability of mammalian sperm.

How has Guinea learnt from the response to outbreaks? A learning health system analysis.

Introduction: Learning is a key attribute of a resilient health system and, therefore, is central to health system strengthening. The main objective of this study was to analyse how Guinea's health system has learnt from the response to outbreaks between 2014 and 2021.

Methods: We used a retrospective longitudinal single embedded case study design, applying the framework conceptualised by Sheikh and Abimbola for analysing learning health systems.

Evaluation of Three Blended Learning Courses to Strengthen Health Professionals' Capacity in Primary Health Care, Management of Sexual and Reproductive Health Services and Research Methods in Guinea.

Background: Three blended courses on Primary Health Care (eSSP), Management of Sexual and Reproductive Health Services (eSSR), and Research Methods (eMR) were developed and implemented between 2017 and 2021 by the Maferinyah National Training and Research Center in Rural Health, a training and research institution of the Ministry of Health in Guinea. The study objectives were to evaluate the reasons for dropout and abstention, the learners' work behavior following the training, and the impact of the behavior change on the achievements of learners' organizations or services.

Methods: We evaluated the three implemented courses in 2021, focusing on levels 3 and 4 of the Kirkpatrick training evaluation model.

Outcomes of blended learning for capacity strengthening of health professionals in Guinea.

Background: Quality human resources constitute an essential pillar of an effective health system. This paper analyzes the outcomes of blended learning for post-Ebola capacity strengthening of health professionals in Guinea.

Methods: Two courses lasting 3 months each (7-8 modules) were developed and implemented: one in Primary Health Care (eSSP) and the other in Sexual and Reproductive Health Services Management (eSSR).

[eLearning approach for capacity strengthening of health professionals in Guinea: A post-Ebola experience].

Introduction: The development of quality human resources for health is an essential pillar of an effective health system. The objective of this study was to describe the implementation process and the results of an eLearning approach for capacity strengthening of health professionals in Guinea.

Method: A descriptive cross-sectional study using a mixed research method was conducted from January 15, 2018 to January 15, 2019.

Dissolving microneedles containing aminolevulinic acid improves protoporphyrin IX distribution.

One important limitation of topical photodynamic therapy (PDT) is the limited tissue penetration of precursors. Microneedles (MNs) are minimally invasive devices used to promote intradermal drug delivery. Dissolving MNs contain drug-associated to polymer blends, dissolving after insertion into skin, allowing drug release.

Theoretical and Experimental Analysis of Protoporphyrin IX Photodegradation Using Multi-Wavelength Light Sources.

Photodynamic procedures have been used in many applications, ranging from cancer treatment to microorganism inactivation. Photodynamic reactions start with the activation of a photosensitizing molecule with light, leading to the production of cytotoxic molecules that promote cell death. However, establishing the correct light and photosensitizer dosimetry for a broadband light source remains challenging.

Development of a system to treat and online monitor photodynamic therapy of skin cancer using PpIX near-infrared fluorescence.

The limited adoption of photodynamic therapy (PDT) around the medical field may be tied to the unpredicted treatment response that an unmonitored therapy could deliver. Given the high variability in the lesions optical and physiological parameters, it is of fundamental importance to monitor PDT, since different lesions require different therapeutic parameters. We developed a system to treat and online monitor PDT of skin cancer, using protoporphyrin-IX (PpIX) near-infrared fluorescence imaging.

An Arabidopsis homolog of the bacterial peptidoglycan synthesis enzyme MurE has an essential role in chloroplast development.

Enzymes encoded by bacterial MurE genes catalyze the ATP-dependent formation of uridine diphosphate-N-acetylmuramic acid-tripeptide in bacterial peptidoglycan biosynthesis. The Arabidopsis thaliana genome contains one gene with homology to the bacterial MurE:AtMurE. Under normal conditions AtMurE is expressed in leaves and flowers, but not in roots or stems.

Malaria in camps for internally-displaced persons in Uganda: evaluation of an insecticide-treated bednet distribution programme.

Malaria is a key health problem among displaced populations in malaria-endemic areas. Mass distribution of insecticide-treated bednets (ITN) to prevent malaria is often carried out in complex emergencies, but there are few data on the outcome or operational effectiveness of such programmes. In June 2001, Medecins Sans Frontieres completed a mass distribution of ITNs (Permanet) to internally displaced persons in Bundibugyo, southwest Uganda, distributing one to four nets per household, and aiming to provide coverage for all residents.
