Published: July 2023

La evaluación de conflictos socioambientales en el Perú, tiene un grado de mucha importancia ya que los mismos pueden distinguirse como los conflictos funcionales; los que mayormente se desarrollan de manera permanente, los mismos permiten de una y otra formar tomar las decisiones acertadas para poder mejorar algunas debilidades que se puede ir mostrando en un determinado momento, y los conflictos disfuncionales; que son los que salen de lo normal ya que se desarrollan de manera conflictiva generando caos y desorden, es por ello a través del presente artículo se tiene como objetivo conocer los principales factores que causas el nacimiento de los conflictos socioambientales y poder de manera específica conocer las debilidades y/o problemas más resaltantes que existieron de manera consecuente y recurrentes. Para ello se utilizó la metodología descriptiva de la revisión de artículos el cual nos dan como resultados que las principales causas para los conflictos socioambiental son por no tener responsabilidad social, cambio climático, falta de educación ambiental, deforestación y mala gobernanza y concluyendo es que se debe establecer una gobernanza adecuada donde haya participación de la sociedad civil organizada desarrollando las actividades con responsabilidad social, conservando los bosques, generar educación ambiental y no se vulnere los derechos de los mismo.

Abstract
Switchbacks are rapid magnetic field reversals that last from seconds to hours. Current Parker Solar Probe (PSP) observations pose many open questions in regard to the nature of switchbacks. For example, are they stable as they propagate through the inner heliosphere, and how are they formed? In this work, we aim to investigate the structure and origin of switchbacks. In order to study the stability of switchbacks, we suppose the small-scale current sheets therein are generated by magnetic braiding, and they should work to stabilize the switchbacks. With more than 1000 switchbacks identified with PSP observations in seven encounters, we find many more current sheets inside than outside switchbacks, indicating that these microstructures should work to stabilize the S-shape structures of switchbacks. Additionally, we study the helium variations to trace the switchbacks to their origins. We find both helium-rich and helium-poor populations in switchbacks, implying that the switchbacks could originate from both closed and open magnetic field regions in the Sun. Moreover, we observe that the alpha-proton differential speeds also show complex variations as compared to the local Alfvén speed. The joint distributions of both parameters show that low helium abundance together with low differential speed is the dominant state in switchbacks. The presence of small-scale current sheets in switchbacks along with the helium features are in line with the hypothesis that switchbacks could originate from the Sun via interchange reconnection process. However, other formation mechanisms are not excluded.
Afterglow Polarizations in a Stratified Medium with Effect of the Equal Arrival Time Surface
Authors: Lan Mi-Xiang , Wu Xue-Feng , Dai Zi-Gao 
Published: July 2023

Abstract
The environment of a γ-ray burst has an important influence on the evolution of jet dynamics and its afterglow. Here we investigate the afterglow polarizations in a stratified medium with the equal arrival time surface (EATS) effect. Polarizations of multiband afterglows are predicted. The effects of the parameters of the stratified medium on the afterglow polarizations are also investigated. We found the influences of the EATS effect on the afterglow polarizations become important for off-axis detections and polarization degree (PD) bumps move to later times with the EATS effect. Even if the magnetic field configurations, jet structure, and observational angles are fixed, polarization properties of the jet emission could still evolve. Here, we assume a large-scale ordered magnetic field in the reverse-shock region and a two-dimensional random field in the forward-shock region. Then, PD evolution is mainly determined by the evolution of the f
32 parameter (the flux ratio between the reverse-shock region and forward-shock region) at the early stage and by the evolution of the bulk Lorentz factor γ at the late stage. Through the influences on the f
32 or γ, the observational energy band, observational angles, and the parameters of the stratified medium will finally affect the afterglow polarizations.
Radio Observations of Six Young Type Ia Supernovae

Published: July 2023

Abstract
Type Ia supernovae (SNe Ia) are important cosmological tools, probes of binary star evolution, and contributors to cosmic metal enrichment; yet, a definitive understanding of the binary star systems that produce them remains elusive. Of particular interest is the identity of the mass-donor companion to the exploding carbon–oxygen white dwarf (CO WD). In this work, we present early-time (first observation within 10 days post-explosion) radio observations of six nearby (within 40 Mpc) SNe Ia taken by the Jansky Very Large Array, which are used to constrain the presence of synchrotron emission from the interaction between ejecta and circumstellar material (CSM). The two motivations for these early-time observations are: (1) to constrain the presence of low-density winds and (2) to provide an additional avenue of investigation for those SNe Ia observed to have early-time optical/UV excesses that may be due to CSM interaction. We detect no radio emission from any of our targets. Toward our first aim, these non-detections further increase the sample of SNe Ia that rule out winds from symbiotic binaries and strongly accreting white dwarfs. and discuss the dependence on underlying model assumptions and how our observations represent a large increase in the sample of SNe Ia with low-density wind constraints. For the second aim, we present a radiation hydrodynamics simulation to explore radio emission from an SN Ia interacting with a compact shell of CSM, and find that relativistic electrons cannot survive to produce radio emission despite the rapid expansion of the shocked shell after shock breakout. The effects of model assumptions are discussed for both the wind and compact shell conclusions.
Rotational Stability After Implantation of Two Different Phakic Toric Intraocular Lenses
Authors: Kilic Deniz , Förster Anika , Mertens Erik , Dick H. Burkhard , Taneri Suphi 
Published: July 2023

Purpose:
To compare clinical outcomes and rotational stability of the toric implantable Collamer lens (TICL) and toric implantable phakic contact lens (TIPCL).

Methods:
Charts were reviewed from January 2011 to January 2023 to identify all TICLs and TIPCLs implanted by a single surgeon. Implant size was generally chosen according to the manufacturer's recommendation, but 15 TIPCLs 0.25 mm larger than recommended to increase vaulting were included.

Results:

Eighty-four TICLs and 98 TIPCLs were identified and yielded excellent refractive and visual results in eyes with high myopic astigmatism at the last follow-up visit. No case of acute glaucoma or cataract induction was observed. In total, 15 (8.2%) rotated lenses were recorded; 2 (2.4%) TICLs and 13 (13.3%) TIPCLs (
P
= .013). Eyes in both groups were similar in preoperative spherical equivalent, cylinder, white-to-white distance, anterior chamber depth (ACD), anterior chamber angle, and mean follow-up times (
P
= .925, .673, .822, .794, .358, and .873, respectively). Average TICL size was larger than TIPCL size (
P
< .001). Rotation of the lenses was positively correlated with cylinder and negatively correlated with ACD but not with vaulting (
P
= .001,
r
= 0.253;
P
= .011,
r
= −0.193;
P
= .488,
r
= −0.057; respectively). Vaulting was positively correlated with preoperative ACD (
P
≤ .001,
r
= .329). In eyes with a rotated TIPCL, preoperative cylinder was higher and ACD was shallower than in eyes with a stable TIPCL (
P
= .001 and .007, respectively). Increasing the implant size had no significant effect on rotation rate (
P
= .685).

Conclusions:
Although both implants were safe and effective in highly myopic eyes, TICL rotated less frequently than TIPCL and required fewer secondary interventions. Rotation was correlated with preoperative cylinder and ACD but not lens vaulting.

Authors: Prot Bernard 
Published: July 2023

Esta nota presenta un texto del etnobotánico André-Georges Haudricourt publicado en 1965 que trata sobre “el origen de las técnicas”. Un breve recordatorio del contexto histórico precede la puesta en evidencia de los argumentos del texto original que sostiene que “la tecnología es la actividad más racional que existe”. Luego, el autor subraya las características de la obra de Haudricourt por medio de varios ejemplos : la misma es concreta, comparativa, histórica. La última parte menciona varios trabajos contemporáneos que se inscriben en la misma perspectiva, particularmente en el campo de la formación y de las ciencias del trabajo.
13 de outubro de 2013 : Assinatura da Convenção de Minamata sobre Mercúrio - Análise a partir da realidade dos mineiros que trabalham na mineração aurífera artesanal e em pequena escala em Madre de Dios, no Peru
Authors: Baudin Carole 
Published: July 2023

Este ano assinalar-se-á o décimo aniversário da assinatura da Convenção de Minamata sobre a utilização de mercúrio. Este acordo, assinado por 128 países, visa proteger a saúde humana, a preservação do ambiente e a biodiversidade, dos efeitos nefastos do mercúrio, centrando-se igualmente na regulamentação da utilização desta substância na mineração aurífera artesanal e em pequena escala. Esta é uma oportunidade de analisar a forma como esta política internacional se traduziu na atividade real das comunidades mineiras da região amazónica de Madre de Dios, no Peru, com as quais o Projeto Wanamei trabalhou. Ao descrever o impacto deste acordo na vida e no trabalho destas comunidades, procuraremos discutir duas linhas de reflexão : 1) a necessidade de repensar as dimensões territorial e temporal destas ações públicas ; 2) a necessidade de mudar o foco das racionalidades subjacentes à ação de uma lógica unicêntrica para uma filosofia pluricêntrica, valorizando as práticas e saberes locais a fim de alcançar soluções sustentáveis.

Abstract
IgE-mediated mast cell activation is a driving force in allergic disease in need of novel interventions. Statins, long used to lower serum cholesterol, have been shown in multiple large-cohort studies to reduce asthma severity. We previously found that statins inhibit IgE-induced mast cell function, but these effects varied widely among mouse strains and human donors, likely due to the upregulation of the statin target, 3-hydroxy-3-methylgutaryl-CoA reductase. Statin inhibition of mast cell function appeared to be mediated not by cholesterol reduction but by suppressing protein isoprenylation events that use cholesterol pathway intermediates. Therefore, we sought to circumvent statin resistance by targeting isoprenylation. Using genetic depletion of the isoprenylation enzymes farnesyltransferase and geranylgeranyl transferase 1 or their substrate K-Ras, we show a significant reduction in FcεRI-mediated degranulation and cytokine production. Furthermore, similar effects were observed with pharmacological inhibition with the dual farnesyltransferase and geranylgeranyl transferase 1 inhibitor FGTI-2734. Our data indicate that both transferases must be inhibited to reduce mast cell function and that K-Ras is a critical isoprenylation target. Importantly, FGTI-2734 was effective in vivo, suppressing mast cell–dependent anaphylaxis, allergic pulmonary inflammation, and airway hyperresponsiveness. Collectively, these findings suggest that K-Ras is among the isoprenylation substrates critical for FcεRI-induced mast cell function and reveal isoprenylation as a new means of targeting allergic disease.

Published: July 2023

Objective:
To analyze the therapeutic response and safety of different treatments for cutaneous leishmaniasis, received by patients in the Program for the Study and Control of Tropical Diseases- PECET-Medellín-Colombia.

Methods:
This is a retrospective cross-sectional study of patients attended at PECET Research Center during 2016-2021. Relevant information regarding sociodemographic characteristics, history of leishmaniasis, characterization of current infection, treatment received, follow-up of therapeutic response and safety was collected from the medical records. Data were analyzed with Pearson's Chi-square association tests and Mann-Whitney U test using statistical software.

Results:
A total of 486 clinical records of patients were analyzed, and 356 received treatment. Eight different therapeutic alternatives (systemic, local and in combination) were analyzed. The therapeutic response of the different alternatives used (except thermotherapy) was higher than 50%. Most frequent adverse events were myalgias, arthralgias and headache, and vesicles for systemic and local treatment, respectively.

Conclusions:
Safety profile and performance of local therapeutic alternatives and combined schemes for the treatment of uncomplicated cutaneous leishmaniasis are an interesting option for the management of the disease.

Published: July 2023

Objective:
To synthesize magnesium oxide nanoparticles using ethanol extract of shoots of Plicosepalus curviflorus (PC-MgONPs) and evaluate the antimicrobial, antioxidant, and anti-proliferative activities of PC-MgONPs.

Methods:
The green synthesized PC-MgONPs were characterized by ultraviolet-visible (UV), Fourier-transform infrared spectroscopy, zeta potential, energy dispersive X-ray, and scanning electron microscopy. Furthermore, we investigated total antioxidant capacity and antimicrobial and anti-proliferative activities using breast cancer cell lines (MDA-231).

Results:
The UV spectrum of PC-MgONPs showed a sharp absorption peak at 300 nm. The presence of magnesium, oxygen, and sodium was confirmed by energy dispersive X-ray analysis. Scanning electron microscopy revealed PC-MgONPs as roughly spherical granular structures with sizes ranging from 20.0 to 76.4 nm. PC-MgONPs showed considerable antimicrobial activities against Escherichia coli, Staphylococcus aureus, methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa and Candida albicans with zones of inhibition of 11-17 mm. In addition, total antioxidant capacity and anti-proliferative activity of PC-MgONPs against MDA-231 cells were dose-dependent.

Conclusions:
The synthesized PC-MgONPs could be a potent antimicrobial, antioxidant and anti-cancer agent, which needs further investigation.

Authors: Kresnoadi Utari , Laksono Valerian , Dahlan Agus 
Published: July 2023

Aims:
The aim of this study was to analyze the induction effect of a combination of N. sativa and bovine bone graft on the expression and ratio of receptor activator of nuclear factor kappa-B ligand expression (RANKL) and osteoprotegerin (OPG) on alveolar bone socket preservation on days 7 and 14.

Settings and Design:
The research incorporated a posttest-only control group design. A total of 56 Cavia cobaya were divided into four groups: a control group, an N. sativa group, a bovine bone graft group, and a combined N. sativa and bovine bone graft group.

Materials and Methods:
The lower incisors of the C. cobaya were extracted with material subsequently being applied to the resulting socket. After the 7th and 14th days, the experimental animals were terminated to enable observation of the socket. Following processing, the tissue was subjected to immunohistochemistry staining consisting of RANKL and OPG antibodies before being observed under a light microscope at × 400.

Statistical Analysis Used:
Statistical analysis was carried out using the one-way ANOVA and Tukey’s honestly significant difference tests.

Results:
A combination of N. sativa and bovine bone graft reduced both RANKL expression and the RANKL/OPG ratio while increasing OPG expression in comparison to the other groups. In all the results obtained, the N. sativa and bovine bone graft combination was significant (P < 0.05) when compared to the control group on both the 7th and 14th days.

Conclusion:
A combination of N. sativa and bovine bone graft reduced both RANKL expression and the RANKL/OPG ratio while increasing OPG expression.
