Conscience Clause
Conscience clauses are legal clauses attached to laws in some parts of the United States and other countries which permit pharmacists, physicians, and/or other providers of health care not to provide certain medical services for reasons of religion or conscience. In many cases, the clauses also permit health care providers to refuse to refer patients to unopposed providers. Those who choose not to refer or provide services may not be disciplined or discriminated against. The provision is most frequently enacted in connection with issues relating to reproduction, such as abortion, sterilization, contraception, and stem cell based treatments, but may include any phase of patient care.

Complex Lymphatic Anomalies
Complex Lymphatic Anomalies (CLA) are characterized by idiopathic boney lesions caused by abnormal lymphatic invasion. The lymphatic network is a one-way system mainly responsible for maintaining fluid homeostasis, lipid absorption, and immune surveillance. CLAs include four diseases with overlapping and distinct clinical features: Gorham-Stout Disease (GSD), General Lymphatic Anomaly (GLA), Kaposiform Lymphangiomatosis (KLA), and Central Conducting Lymphatic Anomaly (CCLA).In order to highlight the known bone involvement of each CLA, their osteopathic phenotypes are described and illustrated below.

Epigenetic Changes and Stress-Related Disorders
Stress is defined as a state of threatened or perceived as threatened homeostasis. Emerging evidence suggests that life-stress experiences can alter the epigenetic landscape and impact the function of genes involved in the regulation of stress response. More importantly, epigenetic changes induced by stressors persist over time, leading to increased susceptibility for a number of stress-related disorders.

AHR and NRF2 in Atopic Dermatitis
Skin is constantly exposed to environmental insults, including toxic chemicals and oxidative stress. These insults often provoke perturbation of epidermal homeostasis and lead to characteristic skin diseases. AHR (aryl hydrocarbon receptor) and NRF2 (nuclear factor erythroid 2-related factor 2) are transcription factors that induce a battery of cytoprotective genes encoding detoxication and antioxidant enzymes in response to environmental insults. In addition to their basic functions as key regulators of xenobiotic and oxidant detoxification, it has been revealed that AHR and NRF2 also play critical roles in the maintenance of skin homeostasis. In fact, specific disruption of AHR function in the skin has been found to be associated with the pathogenesis of various skin diseases, most prevalently atopic dermatitis (AD).

Painful Legs and Moving Toes
Painful Legs and Moving Toes syndrome (PLMT) is a rare neurological movement disorder characterized by involuntary and irregular movements of one or more toes, often together, with moderate to severe diffuse pain at the foot and leg. It can appear on one or both sides and in the upper limbs as well as lower limbs. The etiology of PLMT is still unclear; therefore, the main symptoms of PLMT, including pain in limbs as well as involuntary movements of toes, can be treated only symptomatically, and the outcomes are often unsatisfactory. Central or peripheral nerve injuries have been assumed to be the possible causes of irregular involuntary movements, often accompanied by chronic pain; however, its etiology is unknown in most cases. The management of PLMT is very difficult because of its rare prevalence and obscure pathogenesis, and there have been no clear guidelines for the treatment of PLMT. Oral medications (e.g., GABAergic agents, benzodiazepines, antiepileptics, antidepressants, atypical antipsychotics, beta-blockers, corticosteroids, cannabis, calcitonin, and analgesics) and several therapeutic interventions (e.g., local botulinum neurotoxin-A injection, spinal cord stimulation, anesthetic, and surgical interventions) have been recommended, based on individual experiences from several cases. Its etiology, pathogenesis, and effective treatments should be further discussed.

Solid Lipid Nanoparticle Preparation Techniques
Solid lipid nanoparticles (SLNs) are an alternate carrier system to liposomes, polymeric nanoparticles, and inorganic carriers. SLNs have attracted increasing attention for delivering drugs, nucleic acids, proteins, peptides, nutraceuticals, and cosmetics. These nanocarriers have attracted industrial attention due to their ease of preparation, physicochemical stability, and scalability. These characteristics make SLNs attractive for manufacture on a large scale.

Flecainide
Flecainide is an IC antiarrhythmic drug approved in 1984 from Food and Drug Administration for the suppression of sustained ventricular tachycardia and later for acute cardioversion of atrial fibrillation (AF) and for sinus rhythm maintenance. It is categorized as a Vaughn-Williams Class IC agent based upon its properties of causes a strong degree of sodium channel blockage with slowing cardiac conduction and a minimal effect on ventricular repolarization. Currently, flecainide is mostly used for sinus rhythm maintenance in atrial fibrillation patients without structural cardiomyopathy although recent studies enrolling different patient population demonstrated a good effectiveness and safety profile.

Antidepressants and Circadian Rhythm
Circadian oscillations alter drug absorption, distribution, metabolism, and excretion (ADME) as well as intracellular signaling systems, target molecules (e.g., receptors, transporters, and enzymes), and gene transcription. There is a positive influence of drug dosing-time on the efficacy of depression therapy. On the other hand, antidepressants have also demonstrated to modulate circadian rhythmicity and sleep–wake cycles.

Micro-Implants in Orthodontics and Dentofacial Orthopaedics
Anchorage is one of the most important elements for successful orthodontic treatment. Traditionally, orthodontics employed teeth and extraoral or intraoral appliances for anchorage, often relying on the patient compliance for its effectiveness. Micro-implants (OMIs), also known in orthodontics as temporary anchorage devices (TAD) or mini-implants or mini-screws have been used to realize difficult orthodontic movements. Orthodontic mini-implants can be a powerful aid in resolving challenging malocclusions that require increased anchorage potential. Their use is versatile, minimally invasive, and proves a good ratio between costs and benefits of orthodontic treatments.

Berberine
Berberine is a plant metabolite belonging to the group of isoquinoline alkaloids with strong biological and pharmacological activity. Currently, berberine is receiving considerable interest due to its anticancer activity based on many biochemical pathways, especially its proapoptotic and anti-inflammatory activity. Nonetheless its influence on metabolic disorders and related diseases seems to be equally important and promising.
