Abstract
Echinococcus granulosus causes hydatid cysts, a significant zoonotic and pulmonary parasitic disease that can mimic various pathologies and is often harder to manage than the disease itself. A hydatid cyst is considered a significant health problem in India, Iran, China, and Mediterranean countries, which lack satisfactory environmental health, preventive medicine, and veterinarian services. Echinococcosis continues to be a major community health burden in several countries, and in some terrains, it constitutes an emerging and re-emerging disease. Cystic echinococcosis is the most common human disease of this genus, and it accounts for a significant number of cases worldwide. Herein, a case involving an 11-year-old presenting with fever, dry cough, and right hypochondrial pain is presented, where imaging revealed a hydatid cyst in the lung. Surgical removal of the cyst was achieved through right posterolateral thoracotomy under one-lung ventilation and anesthesia using intubation with a double-lumen endotracheal tube (DLET or DLT), highlighting surgery as the primary treatment despite the lack of consensus on surgical methods. This case underscores the effectiveness of individualized, parenchyma-preserving surgery for even large, uncomplicated cysts, indicating a positive prognosis.

Abstract
One-stage total correction is known to be anatomically unsuitable for correcting tetralogy of fallot (TOF) in a certain proportion of children. Surgeons are thus faced with dilemmas regarding which preliminary operation for the anomaly to do first. Brock's primary postulation suggests that pulmonary trunk and annulus enlargement leading to the correction of the outflow obstruction will favor the subsequent total correction. In line with this, the current article presents two patients who were 6 months and 5 years old. The first patient underwent primary Brock's operation while the second patient had a blocked modified Blalock-Taussig's shunt (MBTS) done off-pump. Following the discontinuation of anti-platelet medications, the MBTS blocked and the patient was subsequently considered for secondary Brock's operation. The outcome of both procedures involved the patients' discharge with uneventful hospital stays and regular follow-ups at specified intervals. Thus, Brock's operation is an excellent preliminary palliative procedure for one-stage total correction of TOF. There is a need to revive 'Brock's procedure' for patients with TOF and poor pulmonary artery anatomy as the procedure of choice. The first direct intra-cardiac operation aimed at directly addressing the pathological anatomy on its Diamond Jubilee Year.

Abstract
Background and Aims Sinus venosus atrial septal defects (SVASDs) constitute a substantial part of atrial septal defects and are usually characterized by anomalous pulmonary venous connection (APVC), causing complications like sinus node dysfunction and arrhythmias. Several surgical approaches are used for treating SVASDs in pediatric patients, including single- and two-patch techniques. The study aimed to prospectively evaluate and compare the safety and efficacy of these two methods with different follow-up periods. Methods Ten patients aged 1-8 years with SVASDs and partial APVC were enrolled in the study at Bhanubhai and Madhuben Patel Cardiac Centre, Karamsad, India, between December 2018 and October 2021. The single-patch (sandwich-patch) technique was used in two patients, whereas the two-patch (dual-patch) technique with autologous pericardium was used in seven. Safety was assessed as the absence of complications in the follow-up periods of 6 months, 1, and 2 years, whereas efficacy was estimated by the preserved sinus rhythm and the development of arrhythmias. Electrocardiographic and echocardiographic methods were used to evaluate both parameters. Results No deaths, reoperations, pulmonary vein, and superior vena cava (SVC) stenosis or phrenic nerve palsy were observed among the 10 patients in the three follow-up periods. Sinus rhythm was arrested in two of the seven patients who underwent two-patch repair, whereas no rhythm disturbances occurred in those who underwent single-patch repair. Conclusion Both techniques used in SVASD repair with autologous pericardium proved to cause the smaller rate of complications in midterm postsurgical phase. However, there is a potentially great risk of the development of sinus node malfunction after the application of the two-patch technique. Therefore, methods avoiding sinus node interference are preferred in patients with partial APVC involving SVC.

Abstract
Although a new right ventricle outflow can be introduced during pulmonary artery reconstruction, it is a suboptimal option as the valved conduits that mimic the natural right ventricular outflow do not grow, and a surgical conduit replacement cannot be averted. This study reported the implementation of hand-made polytetrafluoroethylene (PTFE) tricuspid-valved conduits to rebuild the right ventricular outflow tract in toddlers with truncus arteriosus and risk factors for earlier conduit explant. Herein, we described a case report of a 9-month-old toddler diagnosed in November 2021 with truncus arteriosus type I with ventricular septal defect (VSD) and severe pulmonary arterial hypertension, who has been successfully discharged 20-days postoperative surgical reconstruction with good bi-ventricular functions. Hand-made PTFE tricuspid-valved conduits are efficient in the reconstruction process of the right ventricular outflow tract in children with truncus arteriosus. The conduits are cheap, easily available, and lack potential sensitization.

Abstract
Tetralogy of Fallot (TOF) is a common cyanotic congenital heart disease. Its surgical correction requires ventricular septal defect (VSD) closure and right ventricular outflow tract obstruction (RVOTO) relief, with transannular patch enlargement (TAPE) of the pulmonary valve. The first successful repair of TOF was reported in 1954 and consisted of closure of the VSD through a large right ventriculotomy, and RVOTO relief with TAPE of the pulmonary valve. To predict the intraoperative requirements and postoperative course of patients with this condition, various evaluation indices are available that can provide a good indication of patient prognosis. We performed this study in a male child (age, 1 year, 9 months; weight 8.5 kgs.) who underwent intracardiac repair for TOF as a primary procedure. We calculated the pulmonary vein index (PVI), McGoon ratio, and Nakata index. The McGoon ratio was 1.97, Nakata index was 539.22 mm2/m2, and PVI was 368.12 mm2/m2. The child had an uneventful post‐operative course with no symptoms of low cardiac output syndrome. He was ventilated for 122 h. The length of intensive care unit and hospital stays were 11 and 14 days, respectively. The PVI is a novel indicator offering prognostic indications for pediatric cardiac patients who have undergone surgical correction of TOF.

Abstract
Cor triatriatum is a rare structural congenital cardiac anomaly in which one of the atria chambers is anatomically divided. If left untreated, cor triatriatum can eventually lead to heart failure. This case report describes our experience with two pediatric patients (a three-year-old girl and an 11-month-old male infant) who underwent surgical correction of cor triatriatum. Both patients underwent excision of the cor triatriatum membrane via cardiopulmonary bypass and had an uneventful postoperative recovery with good outcomes. Surgical repair of cor triatriatum sinister provides satisfactory short-term and long-term outcomes with a low risk of requiring additional intervention.

Abstract
The low prevalence of scimitar syndrome along with its varied clinical presentation poses a diagnostic dilemma to the treating clinicians. It usually falls under a large spectrum of conditions called venolobar syndrome. Scimitar involves the partial venous drainage of the right lung to the inferior vena cava (IVC). We share our experience of two cases that were diagnosed as partial anomalous pulmonary venous connection/drainage (PAPVC/PAPVD) on echocardiography but CT scan revealed the underlying scimitar syndrome. Perioperative pulmonary arterial hypertension, intraoperative ventilation strategies for managing associated lung hypoplasia, and postoperative right ventricular dysfunction are a few challenges faced in the perioperative period.

Abstract
Alagille syndrome (ALGS) is a rare autosomal dominant genetic disorder with multisystem involvement including the liver, heart, skeleton, eyes, kidneys, and other organ systems, along with characteristic facial abnormalities. Some patients with ALGS may have isolated involvement of a particular system, such as a heart defect like the tetralogy of Fallot, an atrial septal defect (ASD), a characteristic facial appearance, or an isolated vertebral body anomaly. These individuals may or may not have liver anomalies or other features typically seen in the disorder. We report the case of a four-year-old female child with moderate ostium secundum ASD and branch pulmonary artery stenosis diagnosed since three months of age who presented with classical features of facial dysmorphism, posterior embryotoxon in the right eye, butterfly presentation of the T5 vertebra, delayed mental development, and history of recurrent infections. Bilateral branch pulmonary artery plasty with glutaraldehyde-treated pericardial patch and direct closure of the ASD leaving a patent foramen ovale was performed to correct the cardiac malformations. The surgery was uneventful without any postoperative complications. Currently, as no curative management of the disorder is available, the syndromic medical and surgical approach remains the mainstay in managing this condition.

Abstract
Previous studies have provided evidence indicating that the nuclear orphan receptor RTR plays an important role during embryonic development and in spermatogenesis. In this study, we examine the expression of RTR in murine placenta and several human placental choriocarcinoma cell lines. Northern blot analysis showed high expression of RTR mRNA in placental tissue. In contrast to murine testis, which contains 7.4 and 2.3 kb transcripts, placental tissue expressed only the larger transcript. Examination of RTR expression in murine placental tissue by immunohistochemistry demonstrated the presence of RTR protein in the nuclei of giant trophoblasts and spongiotrophoblasts. RTR mRNA was also expressed in rat choriocarcinoma Rcho-1 cells and in the human placental choriocarcinoma cell lines BeWo, JAR, and JEG-3. In trophoblasts, RTR was co-expressed with the estrogen-related receptors ERR alpha and ERR beta. Giant trophoblast differentiation in Rcho-1 cells, characterized by induction of placental lactogen I (PL-I), was accompanied by a steady decrease in the expression of RTR mRNA and down-regulation of ERR beta expression while levels of ERR alpha mRNA did not change significantly. RTR was able to inhibit ERR alpha-mediated transactivation through the consensus RTR-response element (RTRE) likely by competing with ERR alpha for binding to the RTRE. These results suggest the possibility of cross-talk between RTR and ERR alpha receptor signalling pathways in trophoblasts.

Abstract
A plasmid clone that suppresses galactose toxicity in a gal7 yeast strain has been isolated from a multicopy genomic DNA library. Molecular analysis revealed that the region responsible for the suppression of galactose toxicity corresponds to the ORF YPR030w, which was named MRG19. A CEN-based plasmid carrying the above ORF was unable to suppress the toxicity. Galactokinase activity was substantially reduced in cell extracts obtained from transformants bearing multiple copies of MRG19. Multiple copies of MRG19 were also able to suppress galactokinase expression driven by the CYC1 promoter but not the TEF1 promoter. Multiple copies of MRG19 could not suppress GAL1-driven galactokinase expression in a gal80 strain. However, MRG19-mediated suppression of CYC1-driven galactokinase expression was independent of GAL80 function. These results imply that multiple copies of MRG19 suppress galactokinase expression probably at the level of transcription. In agreement with this idea, multiple copies of MRG19 also suppress beta-galactosidase expression driven by the GAL1 promoter in a GAL80-dependent manner. Disruption of MRG19 leads to an increase in the cell density at stationary phase in synthetic complete medium. MRG19 encodes a previously uncharacterised 124-kDa protein that shows no sequence homology to any known proteins.

Abstract
A suppressor of galactose toxicity in a gal7 yeast strain (lacking galactose 1-phosphate uridyl transferase) has been isolated from a HeLa cell cDNA library. Analysis of the plasmid clone indicated that the insert has an ORF identical to that of hIMPase (human myo-inositol monophosphatase). The ability of hIMPase to suppress galactose toxicity is sensitive to the presence of Li(+) in the medium. A gal7 yeast strain harboring a plasmid containing cloned hIMPase grows on galactose as a sole carbon source. hIMPase mediated galactose metabolism is dependent on the functionality of GAL1 as well as GAL10 encoded galactokinase and epimerase respectively. These results predicted that the UDP-glucose/galactose pyrophosphorylase mediated pathway may be responsible for the relief of galactose toxicity. Experiments conducted to test this prediction revealed that expression of UGP1 encoded UDP-glucose pyrophosphorylase can indeed overcome the relief of galactose toxicity. Moreover, expression of UGP1 allows a gal7 strain to grow on galactose as a sole carbon source. Unlike the hIMPase mediated relief of galactose toxicity, UGP1 mediated relief of galactose toxicity is lithium insensitive. Based on our results and on the basis of available information on galactose toxicity, we suggest an alternative explanation for the molecular mechanism of galactose toxicity.

Abstract
Structural studies on soluble proteins using nuclear magnetic resonance (NMR) spectroscopy and other structural methods in general require large quantities of isotopically enriched proteins. Human interleukin-5 is a disulfide-linked homodimeric cytokine implicated in asthmatic response. The development of a high yield overexpression system for human interleukin-5 is an important prerequisite to using modern multidimensional NMR in the characterization of the solution structure of the protein and to characterize interactions with a soluble receptor domain. Significant amounts of the protein were expressed using an optimized synthetic gene in a high yield expression system. Gene synthesis was accomplished through the ligation of six oligonucleotides composed of optimized codons. The ligated fragments were further amplified by a polymerase chain reaction and then subcloned into the T7 RNA polymerase based overexpression vector pET11a. However, the induced protein accumulated in the form of inclusion bodies. Initially, the protein was solubilized under denaturing conditions and purified in these denaturing conditions by passage through a single S-200 HR sizing column. Finally, protein refolding was initiated in the presence of 2 M urea followed by dialysis. This protocol yielded 40 mg of biologically active, isotope-enriched protein from 4 liters of minimal medium thus facilitating structural studies by NMR. The strategy described may be of immense value in the production of significant quantities of recombinant, eukaryotic proteins for structural and other studies.

Abstract
Characteristics are presented of various new filter materials of polyvinyl chloride--polyacrylonitrile, polyimide, polyaromatic, and of quartz fibers. These filters have been specifically developed for air sampling applications. Included in the presentation are comparative performance characteristics such as: infrared and ultraviolet spectra, inorganic and trace metals analyses, chemical compatibilities and reactivities with various liquids and gases, moisture pick-up, mass per unit area, mechanical properties (tensile strength and elongations), air flows/pressure drops, and particle retention efficiencies. Examples are presented of the increased acceptance of membrane filters in air analyses due to their simplifying tedious conventional procedures and their improvement of sensitivity, precision, and accuracies. Included are the ability of specific synthetic filters to impart optical transparency for analyses of asbestos and other fibers by transmission techniques using oil immersion or dispersion staining, the direct determination of silica on an acrylonitrile membrane by infrared, the direct determination of atmospheric particulate types and the concentrations of each. Other examples given are trace metal analyses by X-ray fluorescence, and gravimetric procedures and scanning electron microscopy techniques for analyses of suspended particulate matter.
