Ecological interaction between Artibeus jamaicensis and Microdesmia arborea in a deciduous forest of central México
Authors: Medina-Bello Kevin I. , Vázquez-Rueda Eduardo , Ayala-Berdón Jorge 
Published: July 2022

La dispersión de semillas es esencial para una gran cantidad de plantas, de manera que estas puedan colonizar nuevos sitios. Entre los dispersores, los murciélagos frugívoros han sido considerados esenciales para el funcionamiento del ecosistema. Aunque el papel de los murciélagos como dispersores de semillas ha sido ampliamente probado, muchas de las interacciones mutualistas entre las plantas y los murciélagos frugívoros aún se desconocen y se ha proporcionado poca evidencia directa de la dispersión de semillas. Como parte de un monitoreo continuo que hemos realizado en la Reserva de la Biosfera Sierra de Huautla, encontramos una pequeña colonia de Artibeus jamaicensis descansando en una cueva cerca de una serie de cultivos utilizados por la población local para producir alimento. En el interior de la cueva encontramos una gran cantidad de cotiledones de Microdesmia arborea (Chrysobalanaceae) en crecimiento, justo debajo de los lugares de descanso utilizados por los murciélagos. Estos cotiledones germinaron a partir de las semillas de los frutos de los que se alimentaron los individuos de A. jamaicensis. Hasta donde sabemos, este es el primer registro que reporta la asociación entre A. jamaicensis y M. arborea. Los cotiledones en crecimiento que encontramos demuestran la importancia de A. jamaicensis para la dispersión y germinación de ciertas especies de plantas, incluso en condiciones desfavorables como el interior de cuevas. De acuerdo con la legislación mexicana, M. arborea se encuentra catalogada como amenazada, por lo que la dispersión de sus semillas por parte de los murciélagos puede ser de vital importancia para su conservación. La dispersión de semillas tiene una gran importancia en un ambiente rodeado de cultivos, donde la regeneración forestal debe desempeñar un papel fundamental en el mantenimiento de la vegetación natural.

Authors: Vázquez-Maldonado Laura Elena , Delgado-Estrella Alberto 
Published: July 2022

En Campeche hay registros de nutria neotropical, Lontra longicaudis, pero la información ecológica es escasa. Se analizó la dieta de esta especie que habita la laguna La Sangría para conocer las preferencias alimentarias a lo largo de un año identificando los restos encontrados en las heces. Los datos se obtuvieron de la revisión de heces y comederos. Una vez por temporada (nortes 2016, secas y lluvias 2017), se recorrieron 11.9 km de la ribera. Se analizaron 126 heces y un comedero colectados en 52 sitios, evaluando el porcentaje de aparición (PA) y amplitud de nicho ecológico (índice de Levins) identificando los restos hasta el máximo nivel taxonómico posible. Se identificaron 7 grupos principales de presas: peces, crustáceos, moluscos, mamíferos, aves, mamíferos y otros. De un total de 16 categorías de presas, los peces fueron los mejor representados al tener un mayor PA y número de géneros, incluida la presencia de pez diablo (especie invasora), seguida de crustáceos y moluscos. No existió variación en las frecuencias de consumo de las presas por temporada climática, pero sí hubo diferencia estadística en la diversidad de especies consumidas. Se confirmó la presencia de 3 especies nativas y 4 posibles nuevos registros de peces como presas. El índice de Levins indicó que la laguna La Sangría presenta una amplitud de nicho para la nutria que tendió a la especialización (0.2078). Al comparar esta dieta con la registrada por otros autores en otras localidades, se evidencia la adaptabilidad trófica de la nutria neotropical y se resalta su valor ecológico.

Published: July 2022

Aims There is an increasing concern of osteoporotic fractures in the ageing population. Low-magnitude high-frequency vibration (LMHFV) was shown to significantly enhance osteoporotic fracture healing through alteration of osteocyte lacuno-canalicular network (LCN). Dentin matrix protein 1 (DMP1) in osteocytes is known to be responsible for maintaining the LCN and mineralization. This study aimed to investigate the role of osteocyte-specific DMP1 during osteoporotic fracture healing augmented by LMHFV. Methods A metaphyseal fracture was created in the distal femur of ovariectomy-induced osteoporotic Sprague Dawley rats. Rats were randomized to five different groups: 1) DMP1 knockdown (KD), 2) DMP1 KD + vibration (VT), 3) Scramble + VT, 4) VT, and 5) control (CT), where KD was performed by injection of short hairpin RNA (shRNA) into marrow cavity; vibration treatment was conducted at 35 Hz, 0.3 g; 20 minutes/day, five days/week). Assessments included radiography, micro-CT, dynamic histomorphometry and immunohistochemistry on DMP1, sclerostin, E11, and fibroblast growth factor 23 (FGF23). In vitro, murine long bone osteocyte-Y4 (MLO-Y4) osteocyte-like cells were randomized as in vivo groupings. DMP1 KD was performed by transfecting cells with shRNA plasmid. Assessments included immunocytochemistry on osteocyte-specific markers as above, and mineralized nodule staining. Results Healing capacities in DMP1 KD groups were impaired. Results showed that DMP1 KD significantly abolished vibration-enhanced fracture healing at week 6. DMP1 KD significantly altered the expression of osteocyte-specific markers. The lower mineralization rate in DMP1 KD groups indicated that DMP1 knockdown was associated with poor fracture healing process. Conclusion The blockage of DMP1 would impair healing outcomes and negate LMHFV-induced enhancement on fracture healing. These findings reveal the importance of DMP1 in response to the mechanical signal during osteoporotic fracture healing. Cite this article: Bone Joint Res 2022;11(7):465–476.
Early intervention with a glycerol throat spray containing cold-adapted cod trypsin after self-diagnosis of common cold: A randomised trial
Authors: Lindberg Fredrik , Nelson Ida , Ranstam Jonas , Riker Donald K. 
Published: July 2022

Background
A glycerol throat spray containing cold-adapted cod trypsin (GCTS) deactivates common cold virus in vitro and decreases pharyngeal rhinovirus load after inoculation in humans. We relied on early self-diagnosis and evaluated two different scales to detect a treatment effect in naturally occurring common colds.

Methods
Adults were enrolled in this randomised, prospective, parallel group, single-blind study to begin treatment six times daily at first sign of a common cold or were assigned to a non-treated group. Jackson’s symptom scale and the 9-item Wisconsin Upper Respiratory Symptom Survey (WURSS)-21 quality of life (QoL) domain were recorded daily by subjects and area under the curve over 12 days (AUC1-12) calculated.

Results
Treatment resulted in reduced symptoms with an AUC1-12 of 45.1 ± 32.5 for Jackson scores compared to 53.8 ± 35.7 in the controls (p = 0.023). AUC1-12 for the 9-item WURSS-21 QoL domain was likewise improved, 113.6 ± 107.7 and 152.7 ± 126.3 (p = 0.006), respectively. During the first four days fewer of the treated subjects (35.3%) used rescue medication than did the control group (50.4%, p = 0.014).

Conclusions
Reduction in common cold symptoms was seen with treatment with a glycerol throat spray containing cold-adapted cod trypsin. This effect was best detected with the 9-item WURSS-21 QoL domain.

Synthesis of aluminium alkylbenzene sulfonate and its behavior as a flow improver for crude oil
Authors: Zhou Zhichao , Zhang Wangyuan , Dong Sanbao , Zhang Jie , Chen Gang 
Published: July 2022

Abstract
Low-molecular flow improvers for crude oil are becoming increasingly important chemical agents for crude oil production in oil fields. In this work, three alkyl benzene sulfonates were synthesized and evaluated as flow improvers for crude oil. The results show that the three flow improvers have an effect on L8401 crude oil (heavy oil). Among them, aluminium dodecylbenzene sulfonate (AlDBS) has the best effect as it reduces the viscosity rate by more than 80%. After adding 900 mg/L AlDBS, the freezing point is lowered by 15 °C. The crude oil flow improvement was proven with microphotographs. The co-crystallization behavior after addition of the agent interacts with the saturated hydrocarbons in the crude oil, which is the reason for lowering the freezing point of crude oil. Moreover, infrared spectroscopy and differential scanning calorimetry analysis (DSC) were used to illustrate the interaction mechanism between low-molecular flow improvers for crude oil and the components in crude oil.

Authors: Budi Mohammad Wahyu Adji Setio 
Published: July 2022

In conducting the state implementation, Indonesia as a state needs regulations in accordance with the national cultural values. The values are mirrored in Pancasilaas the spirit of constitutional law which is The Constitution 1945. Indonesian governmental system is presidential; the president is the state chief and the governmental chief. The state power is in three powers, that are legislative, executive, andjudicial powers. Those three powers have relations in sharing the powers. This practice is not the same as the original theory of Montesquei about power divisions. In the implementation, The Constitution 1945 has supporting institutions. They are People's Consultative Council, House ofrepresentative, President, Supreme Court, Constitutional Council, Judicial Commission, Financial investigator, Police, and the Army.
Non-invasive assessment of tissue sodium content in patients with primary adrenal insufficiency
Authors: Chifu Irina , Weng Andreas Max , Burger-Stritt Stephanie , Bley Thorsten Alexander , Christa Martin , Köstler Herbert , Hahner Stefanie 
Published: July 2022

Objective
Replacement therapy in primary adrenal insufficiency (PAI) with corticosteroids modulates sodium homeostasis. Serum sodium is, however, prone to osmotic shifts induced by several additional factors besides corticosteroids and does not always reliably reflect treatment quality. Non-osmotic tissue storage can be visualized by sodium MRI (23Na-MRI) and might better reflect corticosteroid activity.

Design
Longitudinal study of 8 patients with newly diagnosed PAI and cross-sectional study in 22 patients with chronic PAI is reported here. Comparison was made with matched healthy controls.

Methods
Using a 23Na-MRI protocol on a 3T scanner, relative sodium signal intensities (rSSI) to signal intensities of the reference vial with 100 mmol/L of sodium were determined in the muscle and skin of the lower calf.

Results
In newly diagnosed patients, tissue rSSI (median, range) were reduced and significantly increased after treatment initiation reaching levels similar to healthy controls (muscle: from 0.15 (0.08, 0.18) to 0.18 (0.14, 0.27), P = 0.02; skin: from 0.12 (0.09, 0.18) to 0.18 (0.14, 0.28), P < 0.01). Muscle rSSI was significantly higher in patients with chronic PAI compared to controls (0.19 (0.14, 0.27) vs 0.16 (0.12, 0.20), P < 0.01). In chronic PAI, skin rSSI significantly correlated with plasma renin concentration.

Conclusion

23Na-MRI provides an additional insight into sodium homeostasis, and thus the quality of replacement therapy in PAI, as tissue sodium significantly changes once therapy is initiated. The increased tissue sodium in patients with chronic PAI might be an indication of over-replacement.

Chegamos ao volume 10 (2) de 2021 da Revista do Programa de Pós-Graduação em Economia: Cadernos CEPEC. Este segundo número de 2021 é publicado em um momento no qual a continuidade dos ataques disferidos contra o sistema de pesquisa e ensino superior público e gratuito brasileiro se tornaram mais graves ainda.Os cortes orçamentários e as condições de crescente precariedade das Instituições Federais de Ensino (IF’s) são visíveis em números detalhados e no dia a dia da prática de ensino, inclusive nas intermináveis filas dos Restaurantes Universitários por todo o Brasil.Em dados tratados por Amaral (2022) temos os "números da desconstrução" da educação brasileira, assim como da ciência e tecnologia nacionais. Assim, entre 2014 e 2021 uma queda persistente, saindo do patamar de R$ 130,0 bilhões para o valor entre R$ 90,0 bilhões e R$ 100,0 bilhões, sendo que a variação de 2014 a 2020 – o maior valor e o menor valor da série – foi de R$ (-37,7) bilhões. Esta queda significa uma redução de 28,5% nos recursos da Função Educação. Do mesmo modo o declínio no componente Ciência e Tecnologia foram dramáticos, no ano de 2014 tivemos aplicados valores em torno de R$ 12,0 bilhões e, em 2021, foram aplicados R$ 5,0 bilhões; uma queda de R$ (-6,7) bilhões. Isto representa uma redução de 57,1% nos recursos financeiros aplicados nesta Função. As Universidades Federais foram sobremaneira impactadas, considerando o componente “investimentos”, tivemos valores em 2021, da ordem de R$ 100 milhões, insignificantes frente ao tamanho do sistema e as suas necessidades de aquisição e atualização de equipamentos para os seus laboratórios. De 2014 a 2021 presencia-se uma drástica queda nesses recursos, saindo de R$ 2,8 bilhões e atingindo R$ 100 milhões, uma queda de 96,4%.Frente quadro tão difícil nos resta continuar resistindo e esperançosos que possamos enquanto sociedade brasileira superar o atual momento e estabelecer uma agenda mínima de reconstrução da Ciência, Tecnologia e da Educação nacionais. O futuro ainda está por se disputar.Neste contexto apresentamos este novo volume dos Cadernos CEPEC. A revista traz como de costume seis artigos dentro de um espectro bastante heterodoxo da economia enquanto ciência e neste número trazemos um artigo-resenha inaugurando uma prática necessária de divulgação de resenhas de livros no contexto de análise da Amazônia e do Brasil. Boa leitura e ensejamos que divulguem a produção publicada nos Cadernos CEPEC, inclusive em suas redes sociais.[1]

Background. One of the urgent problem of modern cardiology is the search for markers to assess the risk of CV (cardiovascular) events in patients with CAD.Objective. To evaluate the level of von Willebrand factor (vWF) in the blood plasma of patients with early onset of CAD and the study of the relationship between vWF hyperproduction and the risk of recurrent CV events.Design and methods. We examined 80 patients who underwent acute myocardial infarction and/or surgical treatment of CAD in the amount of percutaneous coronary intervention or coronary artery bypass surgery at the age of up to 55 years (men) and up to 60 years (women).Results. The following predictors of an unfavorable course of coronary artery disease in the examined patients were identified: an increased level of vWF, a higher BMI, and hypoalphacholesterolemia at the inclusion in the study. Among patients with normal vWF, no adverse CV events were recorded after 2 years of observation. A number of factors included in the prognostic model for the development of a recurrent CV event were identified: vWF level, age, BMI, hyperglycemia, and carotid atherosclerosis. Model demonstrated 92.5 % agreement between the forecast and the observation.Conclusions. Elevated plasma vWF levels may serve as an additional risk factor for the development of recurrent CV events in patients with early manifestations of CAD.

Published: July 2022

Background:
Disparities exist in treatment modalities, including arthroscopic surgery, for orthopaedic injuries between high-income countries (HICs) and low- and middle-income countries (LMICs). Arthroscopy training is a self-identified goal of LMIC surgeons to meet the burden of musculoskeletal injury. The aim of this study was to determine the necessary “key ingredients” for establishing arthroscopy centers in LMICs in order to build capacity and expand training in arthroscopy in lower-resource settings.

Methods:
This study utilized semi-structured interviews with orthopaedic surgeons from both HICs and LMICs who had prior experience establishing arthroscopy efforts in LMICs. Participants were recruited via referral sampling. Interviews were qualitatively analyzed in duplicate via a coding schema based on repeated themes from preliminary interview review. Subgroup analysis was conducted between HIC and LMIC respondents.

Results:
We identified perspectives shared between HIC and LMIC stakeholders and perspectives unique to 1 group. Both groups were motivated by opportunities to improve patients’ lives; the LMIC respondents were also motivated by access to skills and equipment, and the HIC respondents were motivated by teaching opportunities. Key ingredients identified by both groups included an emphasis on teaching and the need for high-cost equipment, such as arthroscopy towers. The LMIC respondents reported single-use materials as a key ingredient, while the HIC respondents reported local champions as crucial. The LMIC respondents cited the scarcity of implants and shaver blades as a barrier to the continuity of arthroscopy efforts.

Conclusions:
Incorporation of the identified key ingredients, along with leveraging the motivations of the host and the visiting participant, will allow future international arthroscopy partnerships to better match proposed interventions with the host-identified needs.

Clinical Relevance:
Arthroscopy is an important tool for treatment of musculoskeletal injury. Increasing access to arthroscopy is an important goal to achieve greater equity in musculoskeletal care globally. Developing successful partnerships between HICs and LMICs to support arthroscopic surgery requires sustained relationships that address local needs.
Secure Transmission of Patient Physiological Data in Wireless Body Area Networks Based on Enhanced and Modified RSA Cryptosystem and Run Length Encoding
Authors: V Anusuya Devi , V Kalaivani 
Published: July 2022

Abstract
The remote monitoring system's application in hospitals is getting more attention during the pandemic COVID-19 Lock down period. In this paper, patient physiological information like heart rate, body temperature, ECG, EEG, blood pressure, and glucose level, etc., are gathered by the body sensor networks, and will be transmitted to the doctors for remote treatment and emergency medical services. The confidentiality of the body sensed information is the main challenge while the transmission occurs in the public communication channel. This work helps to provide a security solution with the wireless body area networks, using Enhanced and Modified RSA algorithm (EMRSA) and Run Length Encoding (RLE). The compression algorithms are implemented to reduce the time of the encryption process. Our proposed scheme is a combination of Run Length Encoding Algorithm for data compression, and the Enhanced and modified RSA algorithm (EMRSA) for data encryption in wireless body area networks.
A Non-Sequential Approach for Steganography using Perfect Square Quotient Differencing (NSPSQD)
Authors: Basak Ratan Kumar , Chatterjee Ritam , Das Debashis , Dasgupta Kousik , Dutta Paramartha 
Published: July 2022

Abstract
Data security is considered as one of the prime concerns in digital communication era. Steganography and cryptography are two parallel approaches adopted for protecting such data. Steganography camouflages the secret data into a cover media while cryptography converts it into an unreadable format. In this paper, we propose a non-sequential steganographic scheme by employing Perfect Square Quotient Differencing, where the secret data is embedded non-sequentially in two parallel phases on the two counter parts of a pixel, quotient and remainder. In phase-I, we apply Two Least Significant Bit (2LSB) replacement on the remainder part whereas perfect square quantization is applied on the quotient part in phase-II. A new format of range-table has been introduced to estimate the length of the embedding bits in phase-II. The proposed method secures high embedding capacity (on an average 3bpp) due to 2-phases of embedding at every single pixel. The proposed algorithm has been experimented on a large set of color animated image sequences. To establish the algorithmic efficiency, Peak Signal to Noise Ratio, Mean Square Error, Universal Image Quality Index and Payload Curve have been used as performance measure. The proposed method outperforms in all performance measure as compared with few modern steganography methods. Steganalysis have also been carried out to establish the robustness and security of the proposed against various security threats. Proposed algorithm can be used to protect digital documents in cloud based storage platform.
