Authors: Ji Hangyu , Chu Weiming , Yang Yong , Peng Xin , Song Xiaoli 
Published: July 2024

Objective
To study the mechanism by which conditioned medium of bone marrow mesenchymal stem cells (BMSCs-CM) facilitates the transition of pro-inflammatory polarized microglia to an anti-inflammatory phenotype.

Methods
BV2 cells, a mouse microglia cell line, were transformed into a pro-inflammatory phenotype using lipopolysaccharide. The expression of phenotypic genes in BV2 cells was detected using real-time quantitative PCR (RT-qPCR). Enzyme-linked immunosorbent assay was used to measure inflammatory cytokine levels in BV2 cells co-cultured with BMSCs-CM. The expressions of mitophagy-associated proteins were determined using western blot. The mitochondrial membrane potential and ATP levels in BV2 cells were measured using JC-1 staining and an ATP assay kit, respectively. Additionally, we examined the proliferation, apoptosis, and migration of C8-D1A cells, a mouse astrocyte cell line, co-cultured with BV2 cells.

Results
After co- culture with BMSCs -CM, the mRNA expression of tumor necrosis factor-α (TNF-α) and inducible nitric oxide synthase significantly decreased in pro-inflammatory BV2 cells, whereas the expression of CD206 and arginase-1 significantly increased. Moreover, TNF-α and interleukin-6 levels significantly decreased, whereas transforming growth factor-β and interleukin-10 levels significantly increased. Furthermore, co-culture with BMSCs-CM increased mitophagy-associated protein expression, ATP levels, mitochondrial and lysosomal co-localization in these cells and decreased reactive oxygen species levels. Importantly, BMSCs-CM reversed the decrease in the proliferation and migration of C8-D1A cells co-cultured with pro-inflammatory BV2 cells and inhibited the apoptosis of C8-D1A cells.

Conclusion
BMSCs-CM may promote the transition of polarized microglia from a pro-inflammatory to an anti-inflammatory phenotype by regulating mitophagy and influences the functional state of astrocytes.

Vaccination is a quick and effective way to protect the population against harmful diseases before coming into contact with pathogens in the external environment. One-third of deaths worldwide are caused by infectious diseases caused by viruses, bacteria, or parasites. Over the years, the planet has experienced different epidemics and pandemics such as the Black Death, smallpox, measles, cholera, influenza, and the most recent SARS-CoV-2; these diseases have claimed the lives of many people.
Aims: Determine the social and economic factors that influence the non-compliance with the vaccination schedule at a primary health center in Guanajuato, Mexico.
Study Design: It is a cross-sectional, analytical, quantitative and observational study.
Place and Duration of Study: CAISES Pardo Guanajuato from March to May 2024
Methodology: The sample were 200 surveys of parents of pediatric patients under 6 years of age at CAISES El Pardo in Guanajuato, Mexico.
200 vaccination cards of children under 6 years old were reviewed to determine whether the vaccination schedule was complete or incomplete. Subsequently, a survey was conducted with the guardians or parents of the children to observe their stance on vaccines, their knowledge, and interest in vaccination.
The survey had a construct validity and an intra-observer reliability of Kappa 0.87, and th e inter-observer Kappa was 0.81.
Results: Mothers in free union, as marital status do have the highest rate of non-compliance with their children's vaccination schedule. Although the marital status of the mother did prove to be an important factor in compliance with the vaccination schedule, various other factors affecting the child's vaccination schedule were identified.
Conclusion: This research shows the main causes why mothers do not vaccinate their children in a timely manner, is availability of vaccination center and distance from home yo vaccination center. The socio-economic determinants did not show effect in incomplete vaccination card.

Background: India is rich in tribal population including north-east India. This research of ours is based on viral hepatitis diagnosis (HBV, HCV, HDV. HAV. HEV) and prevalence in the eight north eastern states of India (namely Assam, Arunachal, Nagaland, Sikkim, Tripura, Meghalaya, Manipur, and Mizoram) that are in locations bordering other countries like Bangladesh, Bhutan and Nepal. The article intercompares the viral hepatitis prevalence pattern in tribal and non-tribal patients in the north eastern states of India as well as the overall prevalence pre-COVID-19 and during the COVID-19.
Methodology: This cross-sectional study data on prevalence of viral hepatitis conducted in the 8 north eastern states of India between 2018-2022 has data. two years before the onset of COVID-19 (2018-2019) and 2 years during the COVID-19 (2020-2022). This manuscript presents retrospective comparison on viral hepatitis prevalence between the recruited viral hepatitis patients of tribal and non-tribal origin. This work also compares viral hepatitis prevalence pre-COVID19 and during COVID-19 with no planned work done on COVID-19 diagnostics.
Results: In this study it was observed that the tribal population in northeast India had higher prevalence of viral hepatitis than non-tribals in young adults whereas non-tribal had higher prevalence of viral hepatitis than tribals in older population. Certain tribes like Lushai of Mizoram had higher prevalence of HDV, HCV, HEV. Hepatitis B vaccination status was better in non-tribals than tribals in the recruited patients. Further in certain states like Manipur and Tripura exhibited significant difference in the diagnostic marker prevalence in hepatocellular carcinoma patients and liver cirrhosis patients before COVID and during COVID.
Conclusion: There were differences in the prevalence and risk factors of viral hepatitis between tribal and non-tribal patients of viral hepatitis in northeast India. Further COVID-19 did have influence on the viral hepatitis prevalence in northeast India.

Published: July 2024

Uropathogens are the causative agents of urinary tract infections (UTIs). Although, UTI can be treated with antibiotics but, the increasing prevalence of antibiotic-resistant uropathogens poses a major setback to the treatment of UTIs hence the need to search for alternative therapies. This study is therefore aimed to analyze the antimicrobial properties of the extract of some medicinal plants such as Zingiber officinale, Hibiscus sabdariffa, Justicia carnea, their nanoparticles and honey on common uropathogens are; Staphylococcus aureus, S. saprophyticus, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Proteus vulgaris, Escherichia coli and Candida sp. The antibiogram profile of the test uropathogens was determined using standard assay prior the plant extract and nanosynthesized plant extract assays. The plant extracts were prepared using ethanol, chloroform and hot water as extraction solvents while the nanosynthesis of the plant extracts was performed using standard methods. The antibiogram of the test uropathogens showed that almost all the tested urobacteria were resistant to all the antibiotics used with multiple antibiotics resistance index ranged from 0.3-0.9, E. faecalis having the highest MARI (0.9). On the other hand, all the Candida strains used were resistant to the tested antifungal agents. Out of all the prepared extracts, the ethanol calyx extract of H. sabdariffa was the most effective on the test urobacteria. The nanosynthesized plant extracts however, was effective against all the uropathogens with the 1M nanobased hot water calyx extract of H. sabdariffa displaying the highest growth inhibitory activity on all the test uropathogens. This work revealed that the ethanol calyx extract of H. sabdariffa and nanobased hot water calyx extract of H. sabdariffa can be explored for the development of more effective drugs against MARI uropathogens.

Published: February 2013

AbstractGomesin is an 18‐residue peptide originally isolated from the hemocytes of the Brazilian spider Acanthoscurria gomesiana. A broad spectrum of bioactivities have been attributed to gomesin, including in vivo and in vitro cytotoxicity against tumour cells, antimicrobial, antifungal, anti‐Leishmania and antimalarial effects. Given the potential therapeutic applications of gomesin, it was of interest to determine if an engineered version with a cyclic backbone has improved stability and bioactivity. Cyclization has been shown to confer enhanced stability and activity to a range of bioactive peptides and, in the case of a cone snail venom peptide, confer oral activity in a pain model. The current study demonstrates that cyclization improves the in vitro stability of gomesin over a 24 hour time period and enhances cytotoxicity against a cancer cell line without being toxic to a noncancerous cell line. In addition, antimalarial activity is enhanced upon cyclization. These findings provide additional insight into the influences of backbone cyclization on the therapeutic potential of peptides.
Quantum Dynamical Simulations of the Femtosecond‐Laser‐Induced Ultrafast Desorption of H2 and D2 from Ru(0001)
Authors: Füchsel Gernot , Tremblay Jean Christophe , Klamroth Tillmann , Saalfrank Peter 
Published: February 2013

AbstractWe investigate the recombinative desorption of hydrogen and deuterium from a Ru(0001) surface initiated by femtosecond laser pulses. We adopt a quantum mechanical two‐state model including three molecular degrees of freedom to describe the dynamics within the desorption induced by electronic transition (DIET) limit. The energy distributions as well as the state‐resolved and ensemble properties of the desorbed molecules are analyzed in detail by using the time‐energy method. Our results shed light on the experimentally observed 1) large isotopic effects regarding desorption yields and translational energies and 2) the nonequal energy partitioning into internal and translational modes. In particular, it is shown that a single temperature is sufficient to characterize the energy distributions for all degrees of freedom. Further, we confirm that quantization effects play an important role in the determination of the energy partitioning.

Abstract

The influence of natural dissolved organic matter (DOM) on acute waterborne Cu toxicity was evaluated in the euryhaline copepod Acartia tonsa at 3 different water salinities. Three sources of freshwater DOM (extracted by reverse osmosis) and 2 sources of marine DOM (extracted using a solid-phase technique) were used. Artificial salt water was used to prepare the experimental media. Different combinations of Cu concentrations and DOM sources and concentrations were tested at salinities of 5, 15, and 30 ppt. Toxicity data (48-h median lethal concentration [LC50] values) were calculated based on dissolved Cu concentrations. In a broad view, data showed that increasing salinity was protective against the acute waterborne Cu toxicity. In general, Cu toxicity was also lower in the presence than in the absence of DOM. Toxicity (48-h LC50) values from all treatments at the same salinity showed a positive linear relationship with the dissolved organic carbon (DOC). Thus, the protective effect of DOM against the acute Cu toxicity seems to be dependent mainly on the DOM concentration. However, it seems also to be dependent to some extent on the source of DOM used. In summary, findings reported in the present study clearly indicate that both salinity and DOM (source and concentration) should be taken into account in the development of an estuarine version of the biotic ligand model.

Mantle composition controls the development of an Oceanic Core Complex
Authors: Wilson S. C. , Murton B. J. , Taylor R. N. 
Published: February 2013

AbstractThe thickness and continuity of oceanic crust is variable. Slow‐spreading ridge segments often contain areas of ‘amagmatic’ or tectonic extension, exposing areas of lower‐crust and upper‐mantle, and having little or no recent volcanism. These are interspersed with areas of ‘normal’ volcanic crust generated by ‘robust’ magmatic accretion. Tectonic spreading is accommodated by displacement on low‐angle extensional detachment faults, forming Oceanic Core Complexes. Although ‘amagmatic’ extension appears to be common at slow spreading rates, little is known about the mechanisms that drive the transition from magmatic spreading. Here, we report results from a detailed study of the Mid‐Atlantic Ridge (13°N–14°N) and show, paradoxically, that despite the presence of several Core Complexes, melt production remains similar along the present‐day spreading axis, which erupts homogeneous ‘normal’ mid‐ocean ridge basalt. However, melt production during formation of the older crust off‐axis was derived from substantially lower degrees of melting of a heterogeneous mantle. During this magmatically restricted phase, melt production was limited by source composition. Small volumes of an enriched basalt (M1) were produced, derived from low‐fraction melts of enriched compositional heterogeneities embedded in an otherwise compositionally depleted upper‐mantle, which, in turn, erupted low‐fraction incompatible‐element‐poor basalts (M2). As a consequence of low magma flux, the crust was thin and insufficient to fully accommodate seafloor spreading. Faulting of this thin crust resulted in the development of detachment faults and the formation of OCCs. Thus, we propose that periods of low melt production, resulting directly from depleted, heterogeneous mantle drives the transition from magmatic to amagmatic spreading.
Use of cosmogenic 129I to constrain numerical models of fluid flow in marine sediments: Application to the Blake Ridge Hydrate Province
Authors: Frederick Jennifer M. , Buffett Bruce A. 
Published: February 2013

AbstractConcentrations of cosmogenic iodine, 129I, in the pore fluid of marine sediments often indicate that the pore fluid is much older than the host sediment, even when vertical flow due to sediment compaction is taken into account. Old pore fluid has been used in previous studies to argue for pervasive upward fluid flow and a deep methane source for hydrate deposits. Alternatively, old pore fluid age may reflect more complex flow patterns. We use a two‐dimensional numerical transport model to account for the effects of topography and fractures on pore fluid pathlines when sediment permeability is anisotropic. We find that fluid focusing can cause significant lateral migration as well as regions where downward flow reverses direction and returns toward the seafloor. Longer pathlines can produce pore fluid ages much older than that expected with a one‐dimensional compaction model. For steady‐state models with geometry representative of Blake Ridge (USA), a well‐studied hydrate province, we find pore fluid ages beneath regions of topography and within fractured zones that are up to 70 Ma old. Our results suggest that the measurements of 129I/127I reflect a mixture of new and old pore fluid. However, old pore fluid need not originate at great depths. Methane within pore fluids can travel laterally several kilometers, implying an extensive source region around the deposit. This type of focusing should aid hydrate formation beneath topographic highs.
An experimental investigation on the effect of a perforated fin on free convection heat transfer from a confined horizontal cylinder
Authors: Rezaei Amir Abbas , Ziabasharhagh Masoud 
Published: February 2013

AbstractNatural convection heat transfer from an isothermal horizontal fin attached to a cylinder, confined between two adiabatic walls of constant height is investigated by the Mach–Zehnder interferometry technique. This study is focused on the effect of a perforated fin attached to the bottom of a cylinder while the vertical position of the cylinder (Y ) changes between two walls with a constant distance of W measuring 1.5 times the cylinder diameter. The cylinder's average Nusselt numbers are determined for three ratios of vertical position to its diameter, Y /D = 0.5, 1.5, 2, and 3. The Rayleigh number ranges from 4.5 × 103 to 1.2 × 104. The distance between the walls is chosen to be 1.5 D, that is, an optimum distance at which the Nusselt number is maximum. The effect of the perforated fin on free convection heat transfer is investigated and compared with other works. Results show outstanding enhancement in heat transfer, with a minimum result of 40% and maximum of 90%. © 2013 Wiley Periodicals, Inc.

FUNCTIONAL ASSESSMENT AND TREATMENT OF PERSEVERATIVE SPEECH ABOUT RESTRICTED TOPICS IN AN ADOLESCENT WITH ASPERGER SYNDROME
Authors: Fisher Wayne W. , Rodriguez Nicole M. , Owen Todd M. 
Published: February 2013

AbstractA functional analysis showed that a 14‐year‐old boy with Asperger syndrome displayed perseverative speech (or “restricted interests”) reinforced by attention. To promote appropriate speech in a turn‐taking format, we implemented differential reinforcement (DR) of nonperseverative speech and DR of on‐topic speech within a multiple schedule with stimuli that signaled the contingencies in effect and who was to select the topic. Both treatments reduced perseverative speech, but only DR of on‐topic speech increased appropriate turn taking during conversation. Treatment effects were maintained when implemented by family members and novel therapists.
