Authors: Goswami Swapan Shantiram  
Published: November 2023

Introduction: Body organs and tissue specimens have been preserved in human and veterinary anatomy, pathology museums for years in traditional modified Kaiserling III solution. Wax embedding, epoxy-resin embedding and Plastination techniques have also been tried. However, the use of Carbopol-940 gel as a preservative medium is not mentioned in the literature. Gel preservative medium can prevent leakage, toxic vapors, and irritation of eyes and skin. Aims: Qualitative evaluation of carbopol-940 gel as a preservative medium for specimens in pathology museums compared to modified Kaiserling III solution over one year. Objectives: 1) To qualitatively evaluate physical integrity of mounted tissue specimens stored in Kaiserling III solution and carbopol-940 gel for one year. 2) To qualitatively evaluate physical, chemical and microbiological parameters of Kaiserling III solution and carbopol-940 gel for one year. Materials and methods: In this qualitative cross-sectional study, different organs were mounted in jars containing modified Kaiserling III solution and carbopol-940 gel. The media were monitored for stability by physical tests, chemical test, and microbiological test, before and after the study. The organs were monitored for physical disintegration by observing for tissue shredding. Specimens were histologically assessed before and after the study for tissue integrity. Results showed good stability of the preservative media and good tissue integrity of the specimens over a period of one year.
El retorno a la infancia en la poesía de Asturias
Authors: González Ovies Aurelio Antonio 
Published: November 2023

Pocos, muy pocos son los poetas que escapan al tema que vamos a tratar en este estudio: el regreso a la infancia, el intento de rescatar y reflejar, a través de la literatura, y más en concreto de la poesía, ese paraíso perdido, la Arcadia infantil, la añoranza por esos escenarios relacionados con la naturaleza, con la harmonía íntima con el ambiente y con la inocencia; unos parajes donde el tiempo apenas existía, ni el dolor ni la angustia, protegidos siempre por las figuras familiares principales, los abuelos, los padres, los hermanos. Pocas, muy pocas son las piezas, que no se acerquen a los orígenes y no recuerden aquella convivencia con el mundo rural y todo cuanto de el se desprende: eternidad, luz, libertad, vegetación, despreocupación.

Vamos a hacer, por tanto, un repaso por los nombres más representativos de nuestra literatura, la de Asturias, en busca de las bien distintas y ricas imágenes con las que los poetas nos aproximan a ese entonces y ese cuando en el que se sentían habitantes felices de esos territorios, protagonistas plenos de un mundo que agigantamos a medida que crecemos, que más presente tenemos cuanto más atrás lo dejamos. Un lugar común, ya desde los clásicos latinos, que se convierte en ocasiones en una forma de denuncia por el abandono de los pueblos y la destrucción de la vida tradicional y sencilla, frente a la frialdad de las ciudades, es decir, que les sirve a los autores para introducir otros tópicos como el beatus ille, locus amoenus, la entrañable casa paterna, etc.

La infancia, una etapa que, casi en la totalidad de los que escriben equivale a un tiempo de aventura y de magia, de infinitud de posibilidades y sueños, a años de dicha en un espacio tan privilegiado como idealizado.
To study the clinical course and management of recurrent OSSN in HIV positive patient in Eastern Uttar Pradesh
Authors: Jhunjhunwala Aditi , Bhatt Kriti 
Published: November 2023

We present a case of recurrent OSSN in HIV positive individual and its successful management. Patient presented to us with slow growing painless greyish mass in temporal area in interpalpebral region. He was diagnosed with HIV 2 years back and was on HAART regimen. He underwent excision for a similar looking mass in same eye 2 years back at the same time he was diagnosed with HIV. On local examination, a greyish white raised nodular gelatinous mass with feeder vessel was seen. It did not involve cornea and took up staining with rose bengal stain. complete excision biopsy using no-touch technique with a margin clearance of 4 mm followed by mitomycin-C and the remaining conjunctival defect closed with amniotic membrane graft was done. Histopathology confirmed OSSN. No recurrence was seen at 2-year follow-up.HIV shows a strong relation with OSSN and also with recurrent disease. Histopathology should always be done in interpalpebral mass excision in HIV positive patients as the recurrence rate is higher with more aggressive tumour.

Published: November 2023

Neurofibromatosis (NF), described by von Recklinghausen in 1882, consists of at least two distinct disorders: NF1 (von Recklinghausen's or peripheral neurofibromatosis) and NF2, formerly known as 'central neurofibromatosis." The prevalence of NF is approximately 1 in 4,000, and of NF2, 1 in 50,000. Neurofibromatosis type 1 is a multisystemic neurocutaneous disorder with an autosomal dominant hereditary pattern. Ocular manifestations include plexiform neurofibroma of eyelid, Lisch nodules in iris, optic nerve glioma, glaucoma, sphenoid wing dysplasia. Retinal and choroidal involvement are encountered less frequently. Unusual ocular findings include multiple choroidal nevi, combined hamartoma, choroidal Schwannoma, choroidal melanoma and vaso proliferative retinal tumors.Here we report a case of an 18 year old girl diagnosed with neurofibromatosis type 1 who on routine ocular examination was found to have high myopia in both eyes and on fundus examination had a macula ‘on’ inferior retinal detachment with retinal hole in right eye. Inferior retinal detachment is rarely reported in neurofibromatosis type 1. This case emphasizes the importance of conducting ocular examination even in asymptomatic patients with neurofibromatosis, so that early detection and treatment can prevent vision loss secondary to retinal detachment.

Experimental study on direct shear properties of polypropylene fiber concrete of different scales
Authors: Liang Ninghui , 彭 龙 , REN Lianxi , LIU Xinrong , MAO Jinwang 
Published: November 2023

Abstract
In order to study the shear performance of polypropylene fiber concrete (PFRC), two kinds of polypropylene fine fiber and one kind of polypropylene coarse fiber were selected for incorporation combination, and the direct shear tests of polypropylene fiber concrete under different axial compressive stress were carried out. The damage pattern and shear stress-displacement curve of PFRC under direct shear load were analyzed, the shear damage mode and strength criterion of PFRC were studied, and the shear toughness enhancement effect of polypropylene fiber on concrete was investigated. The results showed that: when the axial compressive stress was below 4 MPa, the PFRC specimens were mainly damaged by slip; when the axial compressive stress was between 4MPa and 15MPa, the specimen mainly suffered shear failure, accompanied by slip failure. In the case of total fiber admixture of 3 kg/m3, the greater the content of coarse polypropylene fibers, the more obvious the enhancement effect; the combination of two types of fine fibers and coarse fibers exhibited better performance compared to using a single type of fine fiber and coarse fiber; fine fibers with a smaller aspect ratio showed a better effect on enhancing the shear strength and shear toughness of concrete. The shear strength and axial compressive stress of PFRC were found to follow the Moore-coulomb criterion.
HessianAuth: A Secure and Efficient Authentication Mechanism for Resource-Constrained IoT Networks
Authors: Dey Debasmita , Ghosh Nirnay 
Published: November 2023

Abstract
The Internet of Things (IoT) constitutes an ecosystem of 6LoWPAN networked resource-constrained devices that entail lightweight security solutions. Owing to the resource limitation of these devices and the delay-sensitive nature of applications running on them, an efficient authentication mechanism is required to validate requesters’ identities with minimum resources and delay. Inthis work, we adopted the Hessian curve, a variant of the elliptic curve and unexplored in Elliptic Curve Cryptography, to propose a distributed authentication mechanism called HessianAuth. Unlike other elliptic curves, it avoids using the expensive “point inversion” curve operation. We leveraged this property to generate digital signatures for authenticating device identities for low-power devices in IoT networks. We simulate a 6LoWPAN environment on the Contiki-based Cooja simulator and empirically show that our approach outperformed three baselines: AES-CBC, the standard Weierstrass curve-based ECC, and the Edward curve-based ECC regarding CPU usage, latency, and power consumption. Finally, we conduct a theoretical security analysis to deduce the validity of mutual authentication done by HessianAuth and its robustness to various identity theft attacks.
Successful management of 15 years late-onset Cytomegalovirus infection complicated with deep venous thrombosis in a kidney transplant patient: a rare case report
Authors: AlNajjar Rami Hassoun , Asaad Rama , Kseibi Hala , Mansour Marah , Al-Shehabi Zuheir , Abrash Mohamad Ali 
Published: November 2023

Abstract
Background
Over the past decades, cytomegalovirus has stood out as one of the most common viruses to cause acute infection in kidney transplantation patients, especially during the first six months, noting that the causes of late and very late infection are still not sufficiently studied. Symptoms of cytomegalovirus infection range from asymptomatic to end-organ infection that may cause graft rejection, which makes it an important factor for investigation and further study. Cytomegalovirus infection showed an increase in the morbidity and mortality of patients in addition to life-threatening complications associated with hypercoagulability and deep vein thrombosis, such as pulmonary embolism.
Case presentation
A65-year-old man with a history of kidney transplant 15 years ago due to idiopathic chronic renal failure, hypertension, diabetes type 2, and ischemic heart disease presented to the emergency department with a complaint of fatigue and hematemesis. His vital signs were normal, and initial tests showed an increase in creatine numbers. An upper gastrointestinal endoscopy was performed, and a biopsy was taken from the superior side of the pylorus, which later revealed signs of chronic gastritis. A cytomegalovirus-polymerase chain reaction was made, which came back positive, and the patient was diagnosed with chronic cytomegalovirus gastritis and treated with ganciclovir. The patient was discharged later with no signs of deep venous thrombosis. Five days after the discharge, the patient was admitted with signs of deep venous thrombosis only in the right lower limb and, after a few days, developed superficial vein thrombosis in his right arm. He was treated for both and left to rest.
Conclusion
Cytomegalovirus can cause deep venous thrombosis through an unknown mechanism that needs to be studied and analyzed. It is important to note that there is only one case report in the medical literature similar to ours (33) to the best of our knowledge, which makes our case considered to be a very rare case. In addition, CMV infection is a predisposing factor for thrombosis that needs to be considered in kidney transplant patients. Therefore, physicians should be aware of this complication and consider using prophylactic anticoagulants for high-risk patients.
Loosely Coupled Under-Resolved LES/RANS Simulation Augmented by Sparse Near-Wall Measurement
Authors: Piroozmand Pasha , Brenner Oliver , Jenny Patrick 
Published: November 2023

Abstract

We investigate scenarios, where only sparse wall shear stress measurements are available, while accurate wall shear stress and velocity profiles are sought. Applying discrete adjoint-based data assimilation, with only near-wall measurements, accurate wall shear stress profiles are achieved at the expense of unrealistic velocity profiles. We therefore add and employ internal reference data generated by performing a relatively cheap hybrid simulation. We modified the dual-mesh hybrid LES/RANS framework recently proposed by Xiao and Jenny~\cite{xiao12} by loosely coupling under-resolved LES in the interior with steady RANS near the walls. The framework was developed in OpenFOAM and tested for flow over periodic hills with Re = 10595. Results show that the devised framework outperforms conventional dual-mesh hybrid LES/RANS and standalone sparse wall-data assimilated RANS models.
Dorsal pulvinar inactivation leads to spatial selection bias without perceptual deficit
Authors: Kaduk Kristin , Wilke Melanie , Kagan Igor 
Published: November 2023

Abstract
The dorsal pulvinar has been implicated in visuospatial attentional and perceptual confidence processing. Pulvinar lesions in humans and monkeys lead to spatial neglect symptoms, including an overt spatial saccade bias during free choices. But it remains unclear whether disrupting the dorsal pulvinar during target selection that relies on a perceptual decision leads to a perceptual impairment or a more general spatial orienting and choice deficit. To address this question, we reversibly inactivated the unilateral dorsal pulvinar by injecting GABA-A agonist THIP while two macaque monkeys performed a color discrimination saccade task with varying perceptual difficulty. We used Signal Detection Theory and simulations to dissociate perceptual sensitivity (d-prime) and spatial selection bias (response criterion) effects. We expected a decrease in d-prime if dorsal pulvinar affects perceptual discrimination and a shift in response criterion if dorsal pulvinar is mainly involved in spatial orienting. After the inactivation, we observed response criterion shifts away from contralesional stimuli, especially when two competing stimuli in opposite hemifields were present. Notably, the d-prime and overall accuracy remained largely unaffected. Our results underline the critical contribution of the dorsal pulvinar to spatial orienting and action selection while showing it to be less important for visual perceptual discrimination.
Use of Recycled Coarse Aggregate for M40 Grade Concrete
Authors: Singh Niranjan , Gupta Ashish 
Published: November 2023

Abstract
Decreasing natural resources of coarse & fine aggregates and growing issues with trash management assistance the beneficiation of trash materials. The quality and uniformity of the recycled aggregate and the concrete generated from it are clearly influenced by the degree of processing and the original concrete's quality, according to research on recycled aggregate concrete. Adhered mortar on the demolished aggregate is the major factor which influences the reuse of recycled aggregate. Different methods are given in the literature to remove the adhered mortar such as mechanical grinding, thermal treatment, chemical treatment etc. In the present study, the demolished waste after testing was taken from the waste concrete present in Structure Engineering Laboratory in B.I.E.T., Jhansi. With a 5 kg hammer, pulverized concrete was broken into coarse aggregates that were 20 mm and smaller. This coarse aggregate derived from the demolished waste, was put in the Los Angles abrasion apparatus for3, 5& 8 min duration. It was observed that after 3 minutes, mortar removal was marginal and after 8 min, abrasion causes loss & rough edges of surface to smooth edges. The optimal mortar removal and maintenance of rough edges was observed after 5 minutes abrasion. Now coarse aggregates obtained after mechanical grinding were immersed in the various concentration of lime of 1N, 1.5N, 2N, 2.5N and 3N for different period of time of 3 days and 7 days. Lime treated aggregate was sieved through 10mm and 20mm sieves and washed with clean water and oven dried subsequently for use in concrete mix design. The natural and recycled coarse aggregates were proportioned by replacing natural coarse aggregates at intervals of 10% by weight with recycled coarse aggregates in the M40 grade concrete. These concrete cubes were tested after 7 and 28 days for cube compressive strength. In this study, It is discovered that RCA concrete has More water is absorbed, the specific gravity is lower, and the bulk density is lower than natural concrete. This results from the existence of adhered mortar on RCA. It is also found that a rise in the % of recycled coarse aggregate decrease the compressive strength of the mix. So RCA is up to 10% can be effectively used to get the compressive strength in order to achieve target strength of the desired design mix.
Współpraca słowackiego biskupa Pavla Hnilicy z polskimi katolikami w latach 1964-1989
Authors: Szumiło Mirosław 
Published: November 2023

Po 1956 r. została nawiązana współpraca między polskimi i słowackimi katolikami, w ramach której Polacy udzielali w różnych formach pomocy dla prześladowanego Kościoła w komunistycznej Czechosłowacji. Akcja ta polegała przede wszystkim na przerzucie zakazanej literatury religijnej oraz przekazywaniu informacji i potajemnym wyświęcaniu księży. Znaczącą rolę odgrywała przy tym słowacka emigracja kościelna z biskupem Pavlem Hnilicą na czele. Hnilica miał zakaz wjazdu do Czechosłowacji, ale do 1978 r. przyjeżdżał regularnie do Polski, aby osobiście organizować kanały przerzutowe do kraju oraz spotykać się z przedstawicielami słowackiego tajnego Kościoła i młodymi Słowakami na oazach Ruchu Światło-Życie. Nawiązał bliską współpracę z polskimi biskupami i księżmi, w szczególności z kardynałami Wyszyńskim i Wojtyłą.
Strategic and Innovative Roles of lncRNAs Regulated by Naturally-derived Small Molecules in Cancer Therapy

Published: November 2023

:
In the field of precision and personalized medicine, the next generation sequencing
method has begun to take an active place as genome-wide screening applications
in the diagnosis and treatment of diseases. Studies based on the determination of
the therapeutic efficacy of personalized drug use in cancer treatment in the size of the
transcriptome and its extension, lncRNA, have been increasing rapidly in recent years.
Targeting and/or regulating noncoding RNAs (ncRNAs) consisting of long noncoding
RNAs (lncRNAs) are promising strategies for cancer treatment. Within the scope of
rapidly increasing studies in recent years, it has been shown that many natural agents obtained
from biological organisms can potentially alter the expression of many lncRNAs
associated with oncogenic functions. Natural agents include effective small molecules
that provide anti-cancer effects and have been used as chemotherapy drugs or in combination
with standard anti-cancer drugs used in routine treatment. In this review, it was
aimed to provide detailed information about the potential of natural agents to regulate
and/or target non-coding RNAs and their mechanisms of action to provide an approach
for cancer therapy. The discovery of novel anti-cancer targets and subsequent development
of effective drugs or combination strategies that are still needed for most cancers
will be promising for cancer treatment.
