Abstract
PURPOSE In 2019, the National Comprehensive Cancer Network (NCCN) recommended genetic testing for all patients with pancreatic ductal adenocarcinoma (PDAC). To evaluate the status of implementation of these guidelines in a loco-regional setting, we performed a retrospective, observational study among patients with newly diagnosed PDAC who received oncologic care at Northeast Georgia Medical Center in Georgia. METHODS Chart abstraction of patients with newly diagnosed PDAC from 1 January 2020 to 31 December 2021 was performed to include information on genetic testing recommendation and completion, and time from diagnosis to testing. The deidentified dataset was then analyzed using appropriate descriptive and associative statistical testing. RESULTS Of the cohort of 109 patients, 32 (29.4%) completed genetic screening; 16 (14.7%) were screened within 10 days of diagnosis. Among the 77 (70.6%) patients who did not receive genetic screening, 45 (41.3%) were not recommended genetic screening despite treatment intent with standard of care therapy. However, 32 (29.4%) were not recommended genetic screening in conjunction with a desire to pursue palliative care/hospice/or due to terminal illness. CONCLUSIONS The study highlighted the gap in implementation of NCCN guideline-directed genetic testing in PDAC patients as only a third underwent testing suggesting the need for systematic processes to facilitate testing. The test was more likely to be completed if done early in the course, especially soon after the diagnosis. Research is needed to explore discussing genetic testing for the large proportion of patients who are terminally ill at diagnosis where genetic screening would potentially benefit the family members.

Abstract
microRNAs direct regulation of various metabolic pathways in plants and animals. miRNAs may be useful in developing novel/elite genotypes, with enhanced metabolites and disease resistance. We examined miRNAs in tomato. In tomato, miRNAs in the carotenoid pathway have not been fully elucidated. We examined the potential role of miRNAs in biosynthesis of carotenoids, transcript profiling of miRNAs and their possible targets (genes and transcription factors) at different development stages of tomato using stem-loop PCR and RT-qPCR. We also identified miRNAs targeting key flavonoid genes, such as chalcone isomerase (CHI), and dihydroflavonol-4-reductase (DFR). Distinct expression profiles of miRNAs and their targets were found in fruits of three tomato accessions, suggesting carotenoid regulation by miRNAs at various stages of fruit development. This was also confirmed using HPLC of the carotenoids. The present study may help in understanding possible regulation of carotenoid biosynthesis. The identified miRNAs can be exploited to enhance biosynthesis of different carotenoids in plants.

Abstract
755 Background: The annual incidence and mortality rates of pancreatic cancer has been rising. We analyzed pancreatic cancer trends by demographics and geographic location. Methods: Data obtained from the Surveillance, Epidemiology, and End Results (SEER) registry 17 were available to assess trends of pancreatic cancer incidence and mortality from 2000 to 2019. Results: The pancreatic cancer incidence and mortality rates consistently increased over time from 2000 to 2019. Incidence of pancreatic cancer was highest in males (14; 95% Cl, 13.9,14.1) and blacks (15.4 95% Cl,15.2, 15.6). The incidence was highest in Alaska (16.2; 95% Cl, 14.1, 18.5), and lowest in Utah (10.7; 95% Cl, 10.4, 11.0). Incidence increased at 0.85% per year (95% Cl, 0.76, 0.92; P < .001). Overall incidence increased significantly for all sex, race, stage sub-groups except for Blacks (APC of 0.04%; 95% Cl, -0.14, 0.22; P = 0.649), and American Indian/Alaska natives (APC of -0.22 %; 95% Cl, -1.33, 0.89; P = 0.679). There was an overall significant increase in incidence across all states except for Alaska. Incidence-based mortality of pancreatic cancer was highest in males (12.6; 95% Cl, 12.5,12.7) and blacks (14.1; 95% Cl, 13.9, 14.3). Mortality was highest in Alaska (15.1; 95% Cl, 13.1,17.3), and lowest in Utah (9.6; 95% Cl, 9.3,9.9). Mortality increased at 0.91% per year (95% Cl, 0.32, 1.50; P = .005). The overall incidence-based mortality increased significantly only in the males APC, 0.95% (95% Cl, 0.36, 1.54; P = 0.003), females APC 1.18 (95% Cl, 0.47, 1.89; P = 0.002) and whites APC 1.05% (95% Cl, 0.45, 1.66; P = 0.002). Furthermore, there was an overall significant increase in incidence-based mortality across all states except for Alaska, Hawaii and Washington. Conclusions: Pancreatic cancer incidence and mortality rates increased overall but differed by demographics and geographic location.

Abstract
Background During the global COVID-19 pandemic, the release of research and data particularly to guide clinical care evolved rapidly and highlights the critical need for timely, and equitable access to medical knowledge and best practices. Specialized medical knowledge has historically been confined to specialists in academic medical centers and disconnected from healthcare professionals in underserved areas. It is important to bridge this gap and democratize knowledge through a model that supports rapid dissemination of best practices to build capacity in areas of need. Methods A Project ECHO partnership was implemented between academic infectious diseases specialists and local healthcare professionals involved in COVID-19 screening, diagnosis and management serving an underserved population. BCM COVID-19 ECHO supported the Access2Health SmartPod COVID-19 clinical operations staffed by a charitable community organization. The SmartPod clinical team were engaged in weekly one-hour ECHO sessions with didactic presentations and case discussions on diverse COVID-19 topics. The program was evaluated at 6 months. COVID 19 ECHO Model ![]()
BCM COVID-19 ECHO Telementoring Program with the United Health Partners in the community BCM COVID-19 ECHO Telementoring Session Topics ![]()
Curriculum developed for the health professionals seeing patients in the SmartPOD and clinics in underserved communities. Results In Fall 2020, BCM COVID-19 ECHO facilitated 10 sessions with an average attendance of 8 healthcare professionals per session. Evaluation results indicated high levels of satisfaction with session content and telementoring partnerships, with 80% expressing intent to apply the knowledge and skills acquired from the sessions to their clinical practice. Conclusion The Project ECHO model successfully engaged healthcare professionals in a continuous learning loop. With the rapid and vast amount of information during the COVID-19 pandemic, it is important to ensure health professionals have equitable access to medical knowledge and feel empowered to implement best practice changes.

Abstract
On 7 February 2021, a catastrophic mass flow descended the Ronti Gad, Rishiganga, and Dhauliganga valleys in Chamoli, Uttarakhand, India, causing widespread devastation and severely damaging two hydropower projects. More than 200 people were killed or are missing. Our analysis of satellite imagery, seismic records, numerical model results, and eyewitness videos reveals that ~27 × 106 cubic meters of rock and glacier ice collapsed from the steep north face of Ronti Peak. The rock and ice avalanche rapidly transformed into an extraordinarily large and mobile debris flow that transported boulders greater than 20 meters in diameter and scoured the valley walls up to 220 meters above the valley floor. The intersection of the hazard cascade with downvalley infrastructure resulted in a disaster, which highlights key questions about adequate monitoring and sustainable development in the Himalaya as well as other remote, high-mountain environments.

Abstract
AIM To explore the potential of Rosellinia sanctae-cruciana an endophytic fungus associated with Albizia lebbeck for pharmaceutically important cytotoxic compounds. METHODS AND RESULTS One novel cytochalasin, named jammosporin A (1) and four known analogues (2-5) were isolated from the culture of the endophytic fungus R. sanctae-cruciana, harboured from the leaves of the medicinal plant A. lebbeck. Their structures were elucidated by extensive spectroscopic analyses including one-dimensional and two-dimensional nuclear magnetic resonance data along with MS data and by comparison with literature reports. In preliminary screening the ethyl acetate extract of the fungal culture was tested for cytotoxic activity against a panel of four cancer cell lines (MOLT-4, A549, MIA PaCa-2 and MDA-MB-231), and found to be active against MOLT-4 with an IC50 value of 10 μg ml-1 . Owing to the remarkable cytotoxic activity of the extract the isolated compounds (1-5) were evaluated for their cytototoxicity against the MOLT-4 cell line by MTT assay. Interestingly, compounds 1-2, 4 and 5 showed considerable cytotoxic potential against the human leukaemia cancer cell line (MOLT-4) with IC50 values of 20·0, 10·0, 8·0 and 6·0 μmol l-1 , respectively, while compound 3 showed an IC50 value of 25 μmol l-1 . This is the first report of the existence of this class of secondary metabolites in R. sanctae-cruciana fungus. CONCLUSION This study discovered a novel compound, named jammosporin A, isolated for the first time from R. sanctae-cruciana, an endophytic fungus of A. lebbeck with anticancer activity against the MOLT-4 cell line. SIGNIFICANCE AND IMPACT OF THE STUDY Rosellinia sanctae-cruciana represents an interesting source of a new compound with bioactive potential as a therapeutic agent against a human leukaemia cancer cell line (MOLT-4).

Abstract
Industrial apple pomace, a biowaste generated during apple processing, is rich in cell wall polysaccharides and phenolics. These biologically active compounds are reported to be highly beneficial from the nutritional and health point of view. In the present study, the total phenolic content in the apple pomace aqueous extract (APE) was estimated and evaluated for its possible antioxidant and hepatoprotective efficacy in carbon tetrachloride (CCl4)-induced liver injury mice model. The aqueous extract exhibited 2,2-diphenyl-2-picrylhydrazyl free radical scavenging activity in vitro. Under in vivo study, mice were treated with APE (200 mg and 400 mg/kg body weight) for 2 weeks prior to the administration of CCl4 (30% v/v). The serum liver injury markers alanine transaminase, aspartate transaminase, and alkaline phosphatase were significantly lowered by APE in a dose-dependent manner. The levels of antioxidant parameters superoxide dismutase (SOD), reduced glutathione (redGSH), and lipid peroxidation were also improved by APE in liver homogenate. Histopathological studies revealed that APE treatment significantly lowered the CCl4-induced necrotic changes in the liver. Furthermore, terminal deoxynucleotidyl transferase deoxyuridine triphosphate nick end-labeling assay showed that CCl4-induced apoptosis in the liver was significantly inhibited by APE in a dose-dependent manner. Immunohistochemistry results showed higher expression of nuclear erythroid 2-related factor 2 (Nrf2) in the liver of the APE-treated mice, a key regulator of antioxidative response. In conclusion, the results of the present study revealed the hepatoprotective efficacy of APE by inhibiting CCl4-induced apoptosis, which is due to its antioxidant activity and the ability to induce Nrf2 protein expression.

Abstract
In both mammalian and Drosophila spermatids, the completely histone-based chromatin structure is reorganized to a largely protamine-based structure. During this histone-to-protamine switch, transition proteins are expressed, for example TNP1 and TNP2 in mammals and Tpl94D in Drosophila. Recently, we demonstrated that in Drosophila spermatids, H3K79 methylation accompanies histone H4 hyperacetylation during chromatin reorganization. Preceding the histone-to-protamine transition, the H3K79 methyltransferase Grappa is expressed, and the predominant isoform bears a C-terminal extension. Here, we show that isoforms of the Grappa-equivalent protein in humans, rats and mice, that is DOT1L, have a C-terminal extension. In mice, the transcript of this isoform was enriched in the post-meiotic stages of spermatogenesis. In human and mice spermatids, di- and tri-methylated H3K79 temporally overlapped with hyperacetylated H4 and thus accompanied chromatin reorganization. In rat spermatids, trimethylated H3K79 directly preceded transition protein loading on chromatin. We analysed the impact of bacterial infections on spermatid chromatin using a uropathogenic Escherichia coli-elicited epididymo-orchitis rat model and showed that these infections caused aberrant spermatid chromatin. Bacterial infections led to premature emergence of trimethylated H3K79 and hyperacetylated H4. Trimethylated H3K79 and hyperacetylated H4 simultaneously occurred with transition protein TNP1, which was never observed in spermatids of mock-infected rats. Upon bacterial infection, only histone-based spermatid chromatin showed abnormalities, whereas protamine-compacted chromatin seemed to be unaffected. Our results indicated that H3K79 methylation is a histone modification conserved in Drosophila, mouse, rat and human spermatids and may be a prerequisite for proper chromatin reorganization.

Abstract
Angiogenesis has a key role in the tumor progression and metastasis; targeting endothelial cell proliferation has emerged as a promising therapeutic strategy for the prevention of cancer. Previous studies have revealed a complex association between the process of angiogenesis and autophagy and its outcome on tumorigenesis. Autophagy, also known as type-II cell death, has been identified as an alternative way of cell killing in apoptotic-resistant cancer cells. However, its involvement in chemoresistance and tumor promotion is also well known. In this study, we used a derivate of natural product magnolol (Ery5), a potent autophagy inducer, to study the association between the autophagy and angiogenesis in both in vitro and in vivo model system. We found that the robust autophagy triggered by Ery5, inhibited angiogenesis and caused cell death independent of the apoptosis in human umbilical cord vein endothelial cells and PC-3 cells. Ery5 induced autophagy effectively inhibited cell proliferation, migration, invasion and tube formation. We further demonstrated that Ery5-mediated autophagy and subsequent inhibition of angiogenesis was reversed when autophagy was inhibited through 3-methyl adenine and knocking down of key autophagy proteins ATG7 and microtubule-associated protein light chain 3. While evaluating the negative regulation of autophagy on angiogenesis, it was interesting to find that angiogenic environment produced by the treatment of VEGF and CoCl2 remarkably downregulated the autophagy and autophagic cell death induced by Ery5. These studies, while disclosing the vital role of autophagy in the regulation of angiogenesis, also suggest that the potent modulators of autophagy can lead to the development of effective therapeutics in apoptosis-resistant cancer.

Abstract
A five-week experiment was conducted to delineate stress-mitigating effects of three different methyl donors in Labeo rohita fingerlings subjected to endosulfan toxicity. Four iso-nitrogenous and iso-caloric feed were prepared with and without supplementation of methyl donors. The feed were basal or control diet (i.e., without methyl donor supplementation), feed supplemented with choline, feed supplemented with betaine and feed supplemented with lecithin. Two hundred and twenty-five fishes were distributed randomly in five treatment groups each with three replicates. The experimental setup were normal water (without endosulfan) and fed with control diet (control group), endosulfan-treated water and fed with control diet (T₁), endosulfan-treated water and fed with choline supplemented feed (T₂), endosulfan-treated water and fed with betaine supplemented feed (T₃) and endosulfan-treated water and fed with lecithin-supplemented feed (T₄). The level of endosulfan in endosulfan treated water was maintained at the level of 1/10 of LC₅₀, that is, 0.2 ppb. During the experiment, growth performances, metabolic enzyme activity and histological examination were done to assess the effect of treatments. The growth performance (percentage weight gain, feed conversion ratio, specific growth rate and protein efficiency ratio) and nutrient digestibility were significantly different (P<0.01) in lecithin, betaine and choline fed group when compared to endosulfan-exposed group fed with basal diet. The liver LDH and MDH activity were significantly (P<0.01) improved in the groups fed with methyl donor supplemented diet. The liver AST and ALT, brain AChE and muscle ALT did not change with supplementation in the diet, but muscle ALT and G6PDH significantly (P<0.01) changed with supplementation. The gill and liver ATPase and intestinal ALP were significantly (P<0.01) noticeably changed in supplemented group. After endosulfan exposure, histopathology alter like slight large vacuolation in hepatocyte and lipoid vacuole were observed and with supplementation normal appearance of liver were observed. The chromosome aberration (karyotype) was observed in endosulfan-exposed group. The result obtained in present study concluded that inclusion of methyl donors, particularly lecithin and betaine, in feed as nutritional supplements has a potential stress-mitigating effect in L. rohita fingerlings.

Abstract
588 Background: AP, a moderate inhibitor of CYP3A4, is a selective neurokinin 1 receptor antagonist recommended by the ASCO guidelines for prevention of high and some moderately emetogenic chemotherapy regimens, including doxorubicin and CPA (AC). CPA is converted to the active 4-OH metabolite primarily by CYP2B6 (48–57%) and by CYP3A4 (12–18%). CYP3A4 also converts 10% of CPA to the N-dechloroethyl metabolite (DCE), which is responsible for neurotoxicity and nephrotoxicity. Because AP is utilized concurrently with CPA, this creates the potential for drug-drug interaction between AP and CPA. The objective of this study was to evaluate the effect of AP on the PK of CPA, 4-OH, and DCE in patients receiving AC. Methods: This double-blinded, placebo controlled, two-period, crossover study included breast cancer patients receiving regimens containing CPA 600 mg/m2 IV for at least two sequential cycles. Prior to each CPA cycle, patients were randomized to receive either oral AP (125 mg on d 1 prior to chemotherapy and 80 mg on d 2 and 3) or placebo for 3 d. During both cycles, patients were also pretreated with ondansetron 24 mg PO and dex 12 mg PO on d 1 and dex 8 mg PO once on d 2 and 3. Rescue anti-emetic medications were permitted. Serial plasma samples were obtained from 0 to 24 h after administration of CPA in combination with AP or placebo in each patient. CPA, 4-OH, and DCE plasma concentrations were determined using HPLC. Area under the plasma versus conc time curve (AUC) was calculated using WinNonlin. Results: 17 patients completed 2 cycles and were evaluated for PK. Geometric mean AUC data for CPA in combination with AP and placebo are summarized in the table. Conclusions: Based on geometric mean ratios ± 90% CI, concurrent administration of AP with CPA did not result in any significant changes in the 4-OH metabolite AUC, but did result in increased parent CPA and decreased DCE drug exposure levels. Based on these results, it is unlikely that aprepitant has a clinically significant effect on the efficacy of CPA. [Table: see text] [Table: see text]
