Physiotherapy Exercise Program for Managing Adhesive Capsulitis in Patients with and without Diabetes: A Pilot Randomized Trial
Adhesive capsulitis (AC), also known as ‘frozen shoulder’, is characterized by the development of dense adhesions and capsular thickening leading to a progressive and painful restriction of shoulder range of motion (ROM) and functional disability . The onset is gradual, usually occurs between the ages of 40 and 60 years and is more common in females and diabetics.Arch Orthop, 2020, Volume 1, Issue 2, p27-39 | DOI: 10.33696/Orthopaedics.1.006
Relationship between Plate Length and Fracture Height as a Predictor of Non-Union in Distal Femur Fractures. A Restrospective Study
The distal femur constitutes the region between the metaphyseal-diaphyseal junction and the femoral condyles. Fractures of this segment, which includes supracondylar and intercondylar fractures, represent between 4 and 7% of all the femur fractures, with an incidence of 37 cases per 100,000 habitants/year. These fractures present a bimodal distribution depending on the injury mechanism.Arch Orthop, 2020, Volume 1, Issue 2, p40-48 | DOI: 10.33696/Orthopaedics.1.007
The Role of the MPFL and MPTL in Patellar Stability – A Biomechanical Study
The medial patellofemoral ligament (MPFL) is a thickened band of tissue that originates from the adductor tubercle and inserts on the proximal medial patella. It is expected that the MPFL, under patellar lateral subluxation, will fail at approximately 12-18 mm of displacement due to the failing of collagen based structures at 20% to 30% elongation.Arch Orthop, 2020, Volume 1, Issue 2, p49-54 | DOI: 10.33696/Orthopaedics.1.008

Clinical and Histological Proof that Surgical Incisions along Skin Folding Lines Result in Optimal Scars
In an early publication, we could show that striae distensae always develop perpendicular to the skin tension lines. In another article, we demonstrated that virtual skin tension lines are identical to the obvious Main Folding Lines; we recommended their use as optimal directions for orthopedic incisions, when inconspicuous scar formation is a prerequisite, as in children, younger adults, and women.Arch Orthop, 2020, Volume 1, Issue 2, p61-67 | DOI: 10.33696/Orthopaedics.1.010
The Nature of Radiation-induced Inherited Recessive Gene Mutations in Drosophila Melanogaster
The nature of gene mutations induced by ionizing radiation in germ cells and transmitted to offspring remains one of the most important problems in radiation genetics of higher eukaryotes. The data accumulated in this field were obtained by different authors under different experimental conditions which does not give a complete insight about the nature of radiation-induced inherited mutations at different genome levels (chromosome, gene, DNA).
Karyotypic Profile of Chronic Myeloid Leukemia in Patients Diagnosed at Tertiary Level in Afghanistan
Balanced translocation resulting in fusion of the Abelson gene (ABL1) from chromosome 9q34 with the breakpoint cluster region (BCR) gene on chromosome 22q11.2 is the pathognomonic molecular driver of CML. The resulting BCRABL 1 fusion gene is both the diagnostic as well as therapeutic target of CML. The first agent with tyrosine kinase inhibitor activity that was licenced in 2000 for treatment of CML patients, was Imatinib, gradually followed by multiple agents with higher efficacy.
Escherichia coli Stress, Multi-cellularity, and the Generation of the Quorum Sensing Peptide EDF
Bacterial communication via quorum sensing (QS) molecules, as well as toxin-antitoxin (TA) gene modules located on bacterial chromosomes are well-studied mechanisms. Escherichia coli mazEF is a stress-induced TA system mediating cell death requiring a QS extracellular death factor (EDF), the pentapeptide NNWNN. MazF is an endoribonuclease specific for ACA sites. During adverse conditions, the activated MazF generates a stress induced translation machinery, composed of MazF-processed mRNAs and selective ribosomes that specifically translate these processed mRNAs.
Constitutively Active Death Receptor Induces Apoptosis in Mammalian Cells
Apoptosis is a physiological response in development and homeostasis of metazoans. Apoptosis is triggered during pathological events as a means to renew affected tissues and eliminate cancer cells. The immune system regulates the extrinsic pathway of apoptosis, where signals such as TNFα or displayed ligands on the surface of immune cells trigger signal cascades by death receptors present on targeted cells.
Commentary on NOBOX Mutations in Premature Ovarian Insufficiency
NOBOX is an ovarian specific transcription factor that plays an important role in follicular growth and survival. Nineteen NOBOX variants have been previously associated with premature ovarian insufficiency (POI). Disease severity in patients with heterozygous and homozygous mutations largely overlap however, hampering genotype-phenotype correlations. We recently reported the first case of biallelic truncating mutations (NM_001080413.3 (NOBOX):c.826C>T, p.(Arg276*) and NM_001080413.3(NOBOX):c.1421del, p.(Gly474Alafs*76)) of NOBOX in two Belgian sisters with POI.
Prevalence of Symptom Clusters in Cancer Patients at First Presentation in Palliative Care Clinic as per Different Disease Groups
Cancer has its own disease burden and patients usually suffer from symptom clusters when they are referred for palliative treatment. Identification of symptom cluster trajectories will help clinician to take into account measures that can optimize quality of life of palliative patients. Therefore the aim of this paper is to determine the overall prevalence of symptoms and symptoms clusters in different disease groups according to etiology at the time of first visit to Palliative care clinic by using HIS Palliative First Assessment note indicating Edmonton symptom scale.
Chimeric Antigen Receptor CAR NK Cells Emerging Immunotherapy for the Treatment of Cancer
Although NK cells are recognized as effector lymphocytes of the innate immune system, they also regulate the adaptive immune response by releasing inflammatory cytokines and developing immunological memory. Unlike other lymphocytes such as T or B cells, NK cells do not express rearrangeable, antigen-specific receptors.
pMB FLASH - Status and Perspectives of Combining Proton Minibeam with FLASH Radiotherapy
Proton minibeam radiotherapy (pMBRT) is an external beam radiotherapy method with reduced side effects by taking advantage of spatial fractionation in the normal tissue. Due to scattering, the delivered small beams widen in the tissue ensuring a homogeneous dose distribution in the tumor. In this review, the physical and biological principles regarding dose distribution and healing effects are explained. In the last decade, several preclinical studies have been conducted addressing normal tissue sparing and tumor control in-vitro and in-vivo, using human skin tissue and mouse or rat models. The major results acquired in these studies are summarized. A further newly emerging therapy method is FLASH radiotherapy, i.e. the treatment using ultra-high dose rates. The possibility of combining these methods in proton minibeam FLASH therapy (pMB FLASH) is worked out. Additionally, technical feasibility and limitations will be discussed by looking at simulations as well as preclinical studies and also pointing out new ways of delivering the desired tumor dose, such as interlacing. We will also highlight the opportunities that emerge regarding high dose radiation, hypofractionation and the combination with immunotherapy.
Flow Cytometric Characterization of Accidental Cell Death Highlights Connections to Regulated Cell Death

Emerging Role of TRPML1 Mucolipin Endolysosomal Channel in Cancer
The transient receptor potential mucolipin 1 (TRPML1) is an endolysosomal channel belonging to the TRP family. Clinically, mutations of TRPML1 have been responsible for a severe lysosomal storage disorder called mucolipidosis type IV.
Manipulating Oxidative Stress Following Ionizing Radiation
It is now well accepted that the ionizing radiation-generated reactive oxygen species (ROS), that constitute ~2/3 of the effects of external beam radiation, do not only produce direct tumor cell death, but also affect the surrounding microenvironment. Moreover, this indirect effect of radiation may result in systemic effects, specifically the initiation of an inflammatory response.
Activation of NLRP3 Inflammosome by N4-Acetyl Cytidine and Its Consequences
N4-acetylcytidine (N4A) is an organic compound and a metabolite of transferrable ribonucleic acid. Its molecular formula is C11H15N3O6. Earlier studies suggest that N4A was mainly found on tRNA and 18S rRNA, while recent studies have shown that there is also a large amount of N4A on mRNA, whose abundance is not even lower than the m7G cap modification carried by mRNA.
