Abstract
PURPOSE/OBJECTIVE(S) Patients diagnosed with Hepatocellular carcinoma (HCC) complicated with portal vein tumor thrombosis (PVTT) have a limited number of treatment options available and are associated with an overall poor prognosis. With the recent developments in the field of radiation therapy, the role of radiotherapy particularly Stereotactic Body radiotherapy (SBRT) has increased as a loco-regional therapy for HCC. This study was planned to evaluate the role of SBRT in Locally advanced HCC complicated with PVTT and its role as loco-regional therapy. MATERIALS/METHODS We conducted a prospective study that included patients diagnosed with HCC complicated with PVTT Child-Turcotte Pugh (CTP) Class A/B with a maximum score of 7, diagnosed on triple phase Contrast-Enhanced - MRI unsuitable for other ablative procedures. Patients with Bilirubin levels > 4 mg/dl, active Hepatitis, CTP score >7, normal liver volume <700cc or history of prior radiotherapy were excluded from the study. Patients underwent a contrast enhanced 4D-CT simulation with abdominal compression and were planned for SBRT using VMAT technique. Patients were followed-up as per Institute protocol. CECT or MRI for a radiological response was done for response assessment using mRECIST criteria version 1.1. A baseline MRI was done at one-month post-SBRT to understand any RT changes in the liver and to differentiate from tumor progression during the response assessment at three months. RESULTS A total of 22 patients with HCC were recruited and received SBRT to PVTT, with a dosage between 30-42 Gy over 6 fractions treated on alternate days. Patients were assessed post-treatment with triphasic CE-MRI every 3 months as per institute protocol. Five patients had achieved Complete response in form of Portal vein recanalization. Three patients had Partial response to the treatment. Seven patients maintained stable disease status whereas six patients had disease progression during the entire course of treatment. The response rate (CR+PR) to treatment was 36.3% at the time of analysis. The Overall Response rate (CR+PR+SD) was 69%. No grade 3 or 4 toxicities were observed and treatment was tolerated well by patients. Kaplan-Meier method was applied to calculate the survival probability at various follow-up intervals. The median time for overall survival was 25 months ((95% CI: 15-35). Out of the 22 subjects included in the study, 6 patients died. There was a 78% survival probability at 12 months and a 68% survival probability at 18 months of follow-up. CONCLUSION This prospective single-arm study demonstrated the vital role of SBRT in the treatment of Hepatocellular carcinoma with Portal vein tumor thrombosis and its efficacy in terms of achieving excellent local control with relatively lesser toxicities compared with existing treatment modalities. Patients have shown benefit post-treatment in terms of thrombus reduction and restoration of Portal vein flow making them suitable for further treatment like Resection or TACE.

Abstract
PURPOSE/OBJECTIVE(S) Biological Response in Hepatocellular carcinoma (HCC) is measured in terms of serum alpha-fetoprotein (AFP) which is elevated in nearly 60% HCC patients at baseline and is directly related to the severity of the disease. This biological response is defined as the reduction of more than 50% from the baseline levels and is associated with an increased percentage of tumor necrosis and is directly related to increased loco-regional control. Patients diagnosed with HCC have very limited treatment modalities. With the recent advances in the field of radiation therapy and the development of Stereotactic Body radiotherapy (SBRT), the role of radiotherapy has increased as a loco-regional modality for HCC. In this single-arm prospective study, we evaluated the biological response post-SBRT in patients diagnosed with HCC. MATERIALS/METHODS We conducted a prospective study that included patients diagnosed with HCC with baseline elevation of serum AFP, Child-Turcotte Pugh (CTP) Class A/B with a maximum score of 7. Patient's serum AFP levels were recorded at baseline, pre-treatment, and post-treatment. The biological response was measured at 3 months post-treatment and compared with the baseline serum AFP levels using Wilcoxon signed rank test. RESULTS A total of 14 patients with HCC were recruited and received SBRT to the target lesion, with a dose between 30-42 Gy over 6 fractions treated on alternate days. Patients were assessed post-treatment at one month with triphasic CEMRI and serum AFP levels. 12 out of 14 patients (85.71%) had a biological response at 3 months follow-up and levels showed further decline unless a progression was found. The median (IQR) serum AFP level was 1131 ng/ml (359-5668 ng/ml) at baseline. Post-treatment serum AFP levels had a median (IQR) value of 156 ng/ml (15-372 ng/ml) showing a near reduction of 86% from baseline, which was significant. 2/14 pts (14.28%) showed no reduction or even increase in serum AFP levels post-treatment. CONCLUSION This prospective single-arm study demonstrated the vital role of SBRT in the treatment of HCC and its importance in achieving a better disease control. The response was achieved in 86% of patients with marked reduction of nearly 90% in serum AFP levels as compared to the baseline and increased median OS and PFS as compared to patients not receiving radiotherapy. Further prospective studies are warranted to confirm our findings.

Abstract
PURPOSE/OBJECTIVE(S) Shorter palliative hypo-fractionated radiotherapy regimens given concurrently with chemotherapy, preferably cisplatin (radiosensitizer), increase response rates with acceptable toxicity, leading to better compliance of patients with locally advanced squamous cell carcinoma of the head and neck (LAHNSCC) in whom late toxicities due to chemoradiotherapy are less relevant. This single institution prospective interventional phase II study was conducted with the goal of achieving high rates of locoregional control with acceptable treatment-related toxicity. MATERIALS/METHODS In this prospective interventional phase- II study, 60 patients with LAHNSCC (treatment naive), the majority in stage IVB and ECOG PS ≤ 3, were treated with QUAD SHOT RT using the conventional 2D technique (14Gy in 4 fractions on 2 consecutive days twice daily with a 6-hour interval between the two fractions) and concurrent cisplatin (CDDP) at a dose of 6 mg/m2. This treatment was repeated at 4-week intervals for 2 additional cycles if tumor progression did not occur. The Kaplan-Meier method was used to determine survival probability for progression-free survival (PFS) and overall survival (OS). Descriptive statistics with number and percentage were used for each toxicity and tumor response at different time points. A P value of less than 0.05 was considered significant. RESULTS In our study, all patients received at least one cycle of QUADSHOT chemoradiotherapy (CTRT), while 35 and 18 patients received the 2nd and 3rd QUADSHOT CTRT, respectively. Of the patients who completed the first cycle of QUADSHOT CTRT, 27 (45%) patients had a partial response (PR) and 22 (36.7%) had stable disease (SD). Of the patients who completed the second cycle QUADSHOT CTRT, 77.2% had SD, while 11.4% had PR and 11.4% had PD. After the 3rd QUADSHOT CTRT, 72.2% had SD, while 11.1% had PR and 16.7% had PD. The overall response rate (SD +PR) in our study was 81%, 88.6%, and 83% after the 1st, 2nd, and 3rd QUADSHOT CTRT, respectively. After the 3rd QUADSHOT CTRT, no patient showed grade 4 toxicity. Most patients had grade I/ II toxicities e.g., skin (grade I -83%), mucositis (grade II -50%), salivary gland toxicity (grade II -50%), grade I laryngitis (83.3%). Grade- III oral mucositis and pharyngitis were seen in 27% and 6.7% of patients, respectively. Median OS and PFS were 7.9 months and 6.2 months, respectively. CONCLUSION Concurrent chemotherapy acts as a radiosensitizer and provides a synergistic effect when coupled with hypo-fractionated radiation, resulting in more effective control of locoregional disease in locally advanced head and neck tumors with acceptable toxicities. This study is hypothesis-generating and may serve as a basis for developing optimal CTRT regimens for patients with LAHNSCC who are not suitable for curative treatment.

Role of pinch in Argon impurity transport in ohmic discharges of Aditya-U Tokamak. Sci Rep 2023; 13:16087. [PMID: 37752170 PMCID: PMC10522584 DOI: 10.1038/s41598-023-42746-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2023] [Accepted: 09/14/2023] [Indexed: 09/28/2023] Open
Abstract
We present experimental results of the trace argon impurity puffing in the ohmic plasmas of Aditya-U tokamak performed to study the argon transport behaviour. Argon line emissions in visible and Vacuum Ultra Violet (VUV) spectral ranges arising from the plasma edge and core respectively are measured simultaneously. During the experiments, space resolved brightness profile of Ar1+ line emissions at 472.69 nm (3p44s 2P3/2-3p44p 2D3/2), 473.59 nm (3p44s 4P5/2-3p44p 4P3/2), 476.49 nm (3p44s 2P1/2-3p44p 2P3/2), 480.60 nm (3p44s 4P5/2-3p44p 4P5/2) are recorded using a high resolution visible spectrometer. Also, a VUV spectrometer has been used to simultaneously observe Ar13+ line emission at 18.79 nm (2s22p 2P3/2-2s2p2 2P3/2) and Ar14+ line emission at 22.11 nm (2s2 1S0-2s2p 1P1). The diffusivity and convective velocity of Ar are obtained by comparing the measured radial emissivity profile of Ar1+ emission and the line intensity ratio of Ar13+ and Ar14+ ions, with those simulated using the impurity transport code, STRAHL. Argon diffusivities ~ 12 m2/s and ~ 0.3 m2/s have been observed in the edge (ρ > 0.85) and core region of the Aditya-U, respectively. The diffusivity values both in the edge and core region are found to be higher than the neo-classical values suggesting that the argon impurity transport is mainly anomalous in the Aditya-U tokamak. Also, an inward pinch of ~ 10 m/s mainly driven by Ware pinch is required to match the measured and simulated data. The measured peaked profile of Ar density suggests impurity accumulation in these discharges.

Abstract
We report the first search for a nonstandard-model resonance decaying into τ pairs in e^{+}e^{-}→μ^{+}μ^{-}τ^{+}τ^{-} events in the 3.6-10 GeV/c^{2} mass range. We use a 62.8 fb^{-1} sample of e^{+}e^{-} collisions collected at a center-of-mass energy of 10.58 GeV by the Belle II experiment at the SuperKEKB collider. The analysis probes three different models predicting a spin-1 particle coupling only to the heavier lepton families, a Higgs-like spin-0 particle that couples preferentially to charged leptons (leptophilic scalar), and an axionlike particle, respectively. We observe no evidence for a signal and set exclusion limits at 90% confidence level on the product of cross section and branching fraction into τ pairs, ranging from 0.7 to 24 fb, and on the couplings of these processes. We obtain world-leading constraints on the couplings for the leptophilic scalar model for masses above 6.5 GeV/c^{2} and for the axionlike particle model over the entire mass range.

Fat mass: a novel digital biomarker for remote monitoring that may indicate risk for malnutrition and new complications in decompensated cirrhosis. BMC Med Inform Decis Mak 2023; 23:180. [PMID: 37705043 PMCID: PMC10498640 DOI: 10.1186/s12911-023-02288-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 09/04/2023] [Indexed: 09/15/2023] Open
Abstract
BACKGROUND Cirrhosis is associated with sarcopaenia and fat wasting, which drive decompensation and mortality. Currently, nutritional status, through body composition assessment, is not routinely monitored in outpatients. Given the deleterious outcomes associated with poor nutrition in decompensated cirrhosis, there is a need for remotely monitoring this to optimise community care. METHODS A retrospective analysis was conducted on patients monitored remotely with digital sensors post hospital discharge, to assess outcomes and indicators of new cirrhosis complications. 15 patients had daily fat mass measurements as part of monitoring over a median 10 weeks, using a Withing's bioimpedance scale. The Clinical Frailty Score (CFS) was used to assess frailty and several liver disease severity scores were assessed. RESULTS 73.3% (11/15) patients were male with a median age of 63 (52-68). There was a trend towards more severe liver disease based on CLIF-Consortium Acute Decompensation (CLIF-C AD) scores in frail patients vs. those not frail (53 vs 46, p = 0.072). When the cohort was split into patients who gained fat mass over 8 weeks vs. those that lost fat mass, the baseline CLIF-C AD scores and WBC were significantly higher in those that lost fat (58 vs 48, p = 0.048 and 11.2 × 109 vs 4.7 × 109, p = 0.031). CONCLUSIONS This proof-of-principle study shows feasibility for remote monitoring of fat mass and nutritional reserve in decompensated cirrhosis. Our results suggest fat mass is associated with greater severity of acute decompensation and may serve as an indicator of systemic inflammatory response. Further prospective studies are required to validate this digital biomarker.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disorder that affects multiple organs. Neuropsychiatric SLE (NPSLE) can manifest with a multitude of neurological and psychiatric symptoms. Psychosis is a rare NPSLE manifestation that can occur at any phase of the illness; 21% of SLE-related psychosis cases occur at the onset of SLE, but the evidence base for this is lacking. We report a case of acute-onset psychosis in a woman that led to a diagnosis of SLE, which was substantiated by physical evaluation and laboratory assessments. Assessment of acute-onset psychosis requires consideration of all differential diagnoses, especially in the presence of atypical features. This case also underscores the importance of physical examination and laboratory investigations in psychosis.

Abstract
We present the first measurement of the ratio of branching fractions of inclusive semileptonic B-meson decays, R(X_{e/μ})=B(B→Xeν)/B(B→Xμν), a precision test of electron-muon universality, using data corresponding to 189 fb^{-1} from electron-positron collisions collected with the Belle II detector. In events where the partner B meson is fully reconstructed, we use fits to the lepton momentum spectra above 1.3 GeV/c to obtain R(X_{e/μ})=1.007±0.009(stat)±0.019(syst), which is the most precise lepton-universality test of its kind and agrees with the standard-model expectation.

Abstract
We report the first measurement of the Michel parameter ξ^{'} in the τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} decay with a new method proposed just recently. The measurement is based on the reconstruction of the τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} events with subsequent muon decay in flight in the Belle central drift chamber. The analyzed data sample of 988 fb^{-1} collected by the Belle detector corresponds to approximately 912×10^{6} τ^{+}τ^{-} pairs. We measure ξ^{'}=0.22±0.94(stat)±0.42(syst), which is in agreement with the standard model prediction of ξ^{'}=1. Statistical uncertainty dominates in this study, being a limiting factor, while systematic uncertainty is well under control. Our analysis proved the practicability of this promising method and its prospects for further precise measurement in future experiments.

Abstract
Abstract Transverse acetabular ligament (TAL) is one of the important ligaments, which provide stability to the hip joint. On rare occasions, it can get ossified leading to limited mobility of the hip joint. Ossified TAL also converts acetabular notch to a foramen and neurovascular structures passing through the notch can get compressed leading to ischaemic symptoms. During routine demonstration of hip bone to undergraduate students, complete ossification of TAL was found in a right sided hip bone. Present case report with this rare finding also includes a short review of literature impressing on embryological and clinical perspectives of ossified TAL. Ossification of this ligament can be caused by defective ossification of hip bone as three secondary ossification centres develop around the acetabulum in triradiate carti-lage. Also, this can be caused due to heterotopic ossification of TAL after an inflammatory or traumatic injury. This ligament is extremely important in total hip replacement surgery being utilised in determining the position of the acetabular component. Anatomical knowledge of abnormal ossification of TAL is imperative in diagnosis and treatment of various pathologies of the hip joint.

Abstract
Background Variable insertions of Palmaris longus (PL) muscle tendon is described by various authors. Presence of extra PL tendon is also described in literature. As autologus tendon grafting is a blooming arena of clinical research at present time, an additional tendinous slip of PL has promising scope for use as an autograft. Case Report We report here bilateral bitendinous distal attachment of PL muscle encountered during routine cadaveric dissection. The additional PL tendon in a multitendinous insertion pattern with optimum length and thickness is indeed an additional advantage from the point of view of autograft harvesting. This has also importance in understanding the unusual, altered symptomatology in compressive conditions. Conclusion Although relatively common, surgeons should be well aware of the various possible aversion of distal attachment of PL which might have significant impact in alteration of symptomatology of neurovascular compressions in the forearm and hand and while choosing an appropriate tendon autograft.

Abstract
Background Here we aim to report the persistent spinous process in the 'pan sacral type' of spina bifida occulta in an asymptomatic male and discuss its clinical significance. The presence of this type of dorsal wall defect with a bony spur attached to it has never been described in the literature to the best of our knowledge after extensive literature search. Our work presents the first anatomic description where the spinous and paraspinous cleft are seen in a sacrum of a live subject. Case Report During a morphometric study of the sacra, normal subject computed tomography imaging (CT) was procured from the Department of Radio-diagnosis. A three-dimensional (3D) image of the sacrum was created using Dicom to Print and Geomagic freeform plus software. A complete dorsal wall defect was observed in a 3D reconstructed sacrum of an adult male. The sacral canal was converted into a groove with a bony spur hanging in the centre. The longitudinal bony spur attached to the lamina was the persistent spinous process. Conclusion Such congenital defects are clinically significant for the anaesthetist during caudal epidural block and for orthopaedic surgeons before any surgical procedure. It may be misdiagnosed as an abnormal bony injury on CT. Thus, it is essential to ensure that patients with congenital anomalies are not treated unnecessarily for spinal fractures.

Abstract
In this paper, the security strength of an enhanced cryptosystem based on interference and the phase-retrieval technique is evaluated. The security strength of the optical cryptosystem was improved through the phase-retrieval technique used to generate a phase-only mask (POM) as the ciphertext. Due to the complex mathematical model of the phase-retrieval technique, it seems that a silhouette problem existing in the conventional interference-based scheme was removed. However, we noted that the random phase mask (RPM) regarded as the only private key was fixed in the encryption path, which is not related to the plaintext and makes it possible to be recovered using a known-plaintext attack (KPA). Moreover, we also found that the RPM has high key sensitivity, and it should be recovered precisely to retrieve information of plaintexts during the attack. Thus, a hybrid KPA where three pairs of known plaintexts and their ciphertexts are regarded as the amplitude and phase constraints to obtain the precise estimation of the RPM is proposed. Then, with the help of the estimated private key, information of the original plaintexts encoded using the cryptosystem under study could be retrieved from an arbitrarily given ciphertext without any knowledge of the private key. Our cryptoanalysis shows that the cryptosystem based on interference and the phase-retrieval technique is vulnerable to the proposed attack, and there is a security leak in it. Numerical simulations have been carried out to demonstrate the performance of our proposed attack.

Abstract
We study B^{+}→π^{+}π^{0}π^{0} using 711 fb^{-1} of data collected at the ϒ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^{+}e^{-} collider. We measure an inclusive branching fraction of (19.0±1.5±1.4)×10^{-6} and an inclusive CP asymmetry of (9.2±6.8±0.7)%, where the first uncertainties are statistical and the second are systematic, and a B^{+}→ρ(770)^{+}π^{0} branching fraction of (11.2±1.1±0.9_{-1.6}^{+0.8})×10^{-6}, where the third uncertainty is due to possible interference with B^{+}→ρ(1450)^{+}π^{0}. We present the first observation of a structure around 1 GeV/c^{2} in the π^{0}π^{0} mass spectrum, with a significance of 6.4σ, and measure a branching fraction to be (6.9±0.9±0.6)×10^{-6}. We also report a measurement of local CP asymmetry in this structure.

Abstract
We search for lepton-flavor-violating τ^{-}→e^{-}α and τ^{-}→μ^{-}α decays, where α is an invisible spin-0 boson. The search uses electron-positron collisions at 10.58 GeV center-of-mass energy with an integrated luminosity of 62.8 fb^{-1}, produced by the SuperKEKB collider and collected with the Belle II detector. We search for an excess in the lepton-energy spectrum of the known τ^{-}→e^{-}ν[over ¯]_{e}ν_{τ} and τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ} decays. We report 95% confidence-level upper limits on the branching-fraction ratio B(τ^{-}→e^{-}α)/B(τ^{-}→e^{-}ν[over ¯]_{e}ν_{τ}) in the range (1.1-9.7)×10^{-3} and on B(τ^{-}→μ^{-}α)/B(τ^{-}→μ^{-}ν[over ¯]_{μ}ν_{τ}) in the range (0.7-12.2)×10^{-3} for α masses between 0 and 1.6 GeV/c^{2}. These results provide the most stringent bounds on invisible boson production from τ decays.

Abstract
Background Accommodation and Vergence disorder are diverse visual anomalies which can interfere with a child's school performance and impair one's ability to function efficiently. Its association with refractive error and its intervention were studied less in Indian myopia children; hence, there is a need for research in such setting. Method One hundred and fifty Indian adolescents aged 10 to 17 years were divided into three refractive error groups (high, moderate, and low myopia). Baseline vision examination and a comprehensive binocular vision assessment were performed on all eligible adolescents. Vision therapy was provided to participants whose parents gave consent on behalf of the children. Chi-square analysis was utilized to look at the association between the groups of refractive errors. To compare the mean constants of the experimental and control groups, a two-way RM ANOVA was performed. Results The most common dysfunction found in low myopia (75.3%), and moderate myopia (54%) was convergence insufficiency. High myopes (62.8%) were found to have combined convergence and accommodative insufficiency followed by accommodative dysfunction (14%) and basic exophoria (6%). In moderate myopia, a significant relationship was found between this dysfunction and refractive error. The experimental group in the overall sample showed statistically significant improvement after vision therapy (P<0.001), in comparison to the control group. Conclusion Refractive error is linked to accommodative and convergence insufficiency. Thus, vergence and accommodative impairment must be tested for all myopic children, and vision therapy should be advised along with spectacle prescription for efficient binocular vision.

Abstract
Background The fibula is a long bone located at the lateral aspect of the leg. Diaphysis of fibula is supplied by one or more nutrient arteries through an opening referred to as the nutrient foramen. Mor-phometric studies of the nutrient foramina of fibulae are very sparse in literature. Materials and Methods This cross-sectional descriptive study was conducted on 51 dry adult human fibulae housed in the department of anatomy, AIIMS, New Delhi. Total fibular length along with the number and location of all nutrient foramina present were recorded. Foraminal indexes (FI) of the fibulae were calculated as well. Results The study revealed that the average length of fibulae was 35.48 ± 1.76 cm. 94% fibulae had a single nutrient foramen and 6 % had two. In fibula with single foramen, the most common location was on the medial crest (50%), followed by between medial crest and posterior border (35%), between the medial crest and interosseous border (8%) and on posterior border (6%). Nutrient foramen was located in middle 1/3rd of shaft in 98 % and in inferior 1/3rd of shaft in 2 % of fibulae. The average foraminal index was 44.85 ± 6.67% with a range of 35.7 to 63.8%. Conclusion Most common location of nutrient foramen in fibula is middle 1/3rd of shaft on the medial crest with dual nutrient foramina in 6% of fibulae. These parameters show variability in different geographical location and population groups. These data may be helpful for anthropologists, forensic experts, radiologists and might guide in harvesting vascularised fibular bone graft.

Abstract
Using the data sample of 980 fb^{-1} collected with the Belle detector operating at the KEKB asymmetric-energy e^{+}e^{-} collider, we present the results of an investigation of the Λπ^{+} and Λπ^{-} invariant mass distributions looking for substructure in the decay Λ_{c}^{+}→Λπ^{+}π^{+}π^{-}. We find a significant signal in each mass distribution. When interpreted as resonances, we find for the Λπ^{+} (Λπ^{-}) combination a mass of 1434.3±0.6(stat)±0.9(syst) MeV/c^{2} [1438.5±0.9(stat)±2.5(syst) MeV/c^{2}], an intrinsic width of 11.5±2.8(stat)±5.3(syst) MeV/c^{2} [33.0±7.5(stat)±23.6(syst) MeV/c^{2}] with a significance of 7.5σ (6.2σ). As these two signals are very close to the K[over ¯]N threshold, we also investigate the possibility of a K[over ¯]N cusp, and find that we cannot discriminate between these two interpretations due to the limited size of the data sample.

Abstract
This report highlights a coronary artery anomaly (CAA) involving three right coronary arteries (RCAs) arising from the anterior aortic sinus and a single left coronary artery (LCA) from the left posterior aortic sinus. Furthermore, each of the three RCAs originated with separate ostia. The 1st RCA was the right conus artery which originated through the anterior ostium. The 2nd RCA from the middle ostium mimicked a typical RCA. The 3rd RCA that originated from the posterior ostium had an initial retro-aortic course and then ran between the ascending aorta and atria. It eventually terminated as the circumflex artery after reaching the left end of the posterior coronary sulcus. The LCA was normal anatomically except that it did not give the circumflex branch. The knowledge of this type of unusual branching pattern of the coronary artery may be useful to clinicians.

Abstract
We study the processes e^{+}e^{-}→ωχ_{bJ}(1P) (J=0, 1, or 2) using samples at center-of-mass energies sqrt[s]=10.701, 10.745, and 10.805 GeV, corresponding to 1.6, 9.8, and 4.7 fb^{-1} of integrated luminosity, respectively. These data were collected with the Belle II detector during special operations of the SuperKEKB collider above the ϒ(4S) resonance. We report the first observation of ωχ_{bJ}(1P) signals at sqrt[s]=10.745 GeV. By combining Belle II data with Belle results at sqrt[s]=10.867 GeV, we find energy dependencies of the Born cross sections for e^{+}e^{-}→ωχ_{b1,b2}(1P) to be consistent with the shape of the ϒ(10753) state. These data indicate that the internal structures of the ϒ(10753) and ϒ(10860) states may differ. Including data at sqrt[s]=10.653 GeV, we also search for the bottomonium equivalent of the X(3872) state decaying into ωϒ(1S). No significant signal is observed for masses between 10.45 and 10.65 GeV/c^{2}.

Abstract
Introduction Suprascapular notch is present at superior border of scapula just medial to coracoid process. This is covered by superior transverse scapular ligament (STSL). Suprascapular nerve passes below this ligament while suprascapular vessels pass above it. STSL ossification is a rare finding with variable incidences in different population groups. Materials and Methods We observed 60 dry bony scapulae, 30 prosected formalin fixed upper limbs with scapula and 10 embalmed cadavers for the presence of ossified STSL. Results There were complete ossification of STSL in two dried bony specimens of sacpula. Conclusion Ossified STSL may be the causative factor for suprascapular neuropathy. The mainstay of management in cases of neuropathy or compression of suprascapular nerve is release of suprascapular ligament by either open or arthroscopic surgical approach. So, it is extremely important to know this type of variation to minimize any damage to related structure and plan the management accordingly.

Abstract
Abstract Meckel's diverticulum (MD) is the most frequent congenital anomaly of the gastrointestinal (GI) tract. Atypical presentations with life threatening complications include intestinal obstruction, intussusceptions, peritonitis, foreign body lodgement in the MD, perforated viscera etc. which require prompt diagnosis. Ectopic gastric and pancreatic tissues are found in up to half of the cases which can escalate the complications. However clinical diagnosis is not easy especially when the presentation is atypical. A high index of clinical suspicion is required to diagnose elusive MD with associated complications. Surgical resection is safe and the gold standard treatment for complicated MD. A case of Meckel's diverticulum with concomitant mesodiverticular band (MDB) in a 13 years old male child presented as intestinal obstruction to emergency department is described which was promptly managed surgically with required pre-operative investigations. The aim of this report is to make clinicians aware about a complicated MD with MDB clinically presenting as small bowel obstruction.
