The 14-Day Rule For In Vitro Human Embryo Research Requires Adjustment: From A Comprehensive Perspective Of Science, Ethics And Policy Research, Xiao Lu, Ming Zhao, Huihui Liu, Tianqing Li, Tao Tan, Weizhi Ji
Bulletin of Chinese Academy of Sciences (Chinese Version)
Since it was proposed, in vitro human embryo research had been following the 14-day rule, which limited in vitro research on human embryos within 14 days after fertilization. With the advancement in embryo culturing technology, this ethical rule has been greatly challenged. In 2021, the International Society for Stem Cell Research (ISSCR) recommended a conditional extension of the existing time limit in ISSCR Guidelines for Stem Cell Research and Clinical Translation, hence the international scientific community has restarted the debate on the 14-day rule. This study systematically analyzed the historical background and controversies of the 14-day rule ethical regulation of …

Brown Anole (Anolis Sagrei) Hoxa5: Insights Into The Divergence Of Hoxa5 Gene Expression And Regulation Across Evolutionarily Divergent Gnathostome Vertebrates, Jennifer A. Lange, Amber L. Rittgers, Adam Davis
Georgia Journal of Science
Hox genes are evolutionarily conserved developmental regulatory genes that function, in part, to pattern the anterior-posterior (AP) axis of organs and organ systems during animal embryonic development. Hoxa5, specifically, is shown to be expressed in the spinal cord, somites, or transient compartments giving rise to the vertebrae and ribs, developing gut, lungs, and limbs of the mouse (Mus musculus). The cis-regulatory elements (CREs), or short DNA sequences, that direct Hoxa5 expression in these embryonic domains have been mapped and functionally tested in the mouse as well. Similar Hoxa5 expression patterns have been observed in chicken ( …

Pro-Apoptosis Activity Of Pogostemon Cablin Benth. Against Nasopharyngeal Carcinoma Through The Bcl-2 Inhibition Signaling Pathway: A Computational Investigation, Aigia Syahraini, Essy Harnelly, Feri Eko Hermanto
Makara Journal of Science
Resistance to chemotherapy and radiotherapy frequently emerges in the later stage of nasopharyngeal carcinoma (NPC) tumorigenesis. The decreased response of NPC to radiotherapy and chemotherapy occurs owing to the inhibition of cancer cell apoptosis by the B-cell lymphoma-2 (BCL-2) protein. Thus, inhibiting BCL-2 protein may become a powerful approach to eliminate NPC through apoptosis regulation. Meanwhile, Pogostemon cablin is reported to exhibit anticancer properties, but there are limited studies on its use for NPC treatment. The objective of this study is to investigate the potential bioactive compounds in P. cablin as anti-apoptosis BCL-2 protein inhibitors using in-silico approach. Natural compounds …

The Use Of Prognostic Markers To Predict Disease Progression And Clinical Outcome In Monoclonal Gammopathy Of Undetermined Significance, Smouldering Multiple Myeloma And Multiple Myeloma., Róisín C. Mcmonagle
International Undergraduate Journal of Health Sciences
Multiple Myeloma (MM) is an incurable plasma cell malignancy with a complex and incompletely understood molecular pathogenesis. Monoclonal Gammopathy of Undetermined Significance (MGUS) and Smouldering Multiple Myeloma (SMM) precede MM, with variable risks and rates of disease progression. The continuing high relapse and death rate in MM cases has prompted research into more accurate prognostic markers to predict progression from MGUS and SMM to MM, as well as identify MM cases with aggressive disease, in order to begin early, targeted and effective therapeutic intervention. Many studies have focused on utilising current markers more effectively, including M-protein, serum-free light chain ratio, …

Hematology/Oncology and Stem Cell Therapy
Bone marrow mesenchymal stromal cells (BM-MSC) are key elements of the hematopoietic niche and participate in the regulatory mechanisms of hematopoietic stem cells (HSC). Hematological diseases can affect MSCs and their functions. However, the dysregulations caused by sickle cell disease (SCD) are not fully elucidated. This work explored changes in BM-MSC and their relationship with age using sickle cell mice (Townes-SS). BM-MSC were isolated from Townes-SS, and control groups Townes-AA and C57BL/6J at 30- and 60-day-old. The BM-MSCs showed no morphological differences in culture and demonstrated the murine MSC-like immunophenotypic profile (Sca-1+, CD29+, CD44+, CD90.2+, CD31-, CD45- and CD117-). Subsequently, …

The Role Of Adenovirus Serotype 5 E4 11k In The Relocalization Of The Cellular P Body Proteins, Kasey A. Karen, La`Quita Randolph, Kevin Neubrecht, Heather Vincent
Georgia Journal of Science
Human adenoviruses are a useful tool to understand basic cellular biology in addition to viral infections. Historically, cellular splicing was first discovered in adenovirus, but other cellular processes, such as double-strand break repair and aggresome formation, have been further elucidated through adenoviral infection. The adenovirus protein E4 11k has been shown to disrupt cytoplasmic processing bodies (p bodies), which are not well-understood but are involved in mRNA metabolism. Several p body proteins were found to be reorganized in the cytoplasm with adenovirus serotype 5 (Ad5) able to cause the colocalization of these p body proteins with aggresomes. The p body …

Background & Objectives We previously described a predictive AAMC model that identifies patients (grade 1, hormone positive) who would not benefit from OncotypeDX testing. The purpose of this study was to validate the AAMC model by assessing distant recurrence-free interval (DRFI) and invasive disease-free survival (IDFS) using TAILORx clinical trial data. Materials & Methods We retrospectively analyzed TAILORx trial data and categorized patients based on the AAMC model. AAMC low-risk patients are those with grade 1 and hormone positive tumors. Kaplan-Meier curves examined DRFI and IDFS. Results Of the total 9195 cases, 2246 (24.4%) were identified as AAMC low-risk. Among …

Hematology/Oncology and Stem Cell Therapy
Multiple myeloma (MM) is the second most common hematologic malignancy with 34,470 estimated new cases in 2022. High-dose therapy followed by autologous hematopoietic cell transplantation (auto-HCT) is a standard treatment for MM even in the era of novel therapies. This is usually done in hospital-based setting, whether in the inpatient or outpatient units. Advanced Care at Home (ACH) represents a virtual hybrid hospital-at-home program that combines a virtual provider-staffed command center with vendor-mediated supply chain capable of delivering high-acuity care in the comfort of patient’s own homes. In our program, we leveraged the existing ACH platform to deliver post-HCT care …

Hematology/Oncology and Stem Cell Therapy
Background: The heterogeneous molecular landscape of cytogenetically normal acute myeloid leukaemia (CN-AML) renders it an ongoing therapeutic challenge. The European Leukaemia Net 2017 guidelines attempted to address this by guiding post-remission therapy according to six prognostically informative mutations. However, its applicability in a South African setting remains elusive due to limited local data. Objectives: This retrospective study aimed to describe a South African CN-AML cohort according to clinicopathological, molecular and treatment outcomes and consequently investigate the local applicability of a triple-mutation testing approach for risk stratification in accordance with the ELN 2017 guidelines, using nucleophosmin (NPM1), fms-like tyrosine kinase internal …

There is a lack of data on the safety and efficacy of peritoneal drain (PD) and chest tube (CT) in the management of effusions in stem cell transplant recipients with veno-occlusive disease (VOD). In this retrospective pediatric study we compared the clinical outcomes and health resource utilization (HRU) in 32 patients with VOD who had a PD placed (PD+) post HCT with 27 patients who did not (PD-). Nine patients had a CT (7 PD+ and 2 PD-). PD+ patients were more likely than PD- patients to have received myeloablative conditioning (100% vs 85.2%; p=0.04) and have severe or very …

Hematology/Oncology and Stem Cell Therapy
Background: Post-transplant cyclophosphamide (PTCy) has shown promising results with low rates of severe graft-versus-host-disease (GVHD), either alone or combined with conventional immunosuppression (CIS). However, studies comparing PTCy with CIS as a GVHD prophylaxis are scarce.
Objective: The study aimed to evaluate the rates of GVHD and survival outcomes in patients undergoing peripheral blood stem cell transplant (PBSCT) from HLA matched related donors (MRD) receiving PTCy based GVHD prophylaxis and to compare it with the outcomes of patients receiving methotrexate (MTX) and cyclosporine-A (CsA) as a GVHD prophylaxis.
Patients and Methods: Seventy-five patients with advanced hematologic malignancies who underwent MRD allogeneic …
