It describes the anatomy and course of each nerve, typical injury locations and mechanisms, clinical features of injuries, and classifications of nerve injuries. Treatment options are also summarized, including nerve mobilization, grafting, and surgical techniques like neurolysis and neurorrhaphy.
807_Ulnar-nerve-and-its-lesions.pptx
The ulnar nerve is involved. Damage to the ulnar nerve results in a characteristic claw hand deformity with the 4th and 5th fingers hyperextended at the MCP joints and flexed at the IP joints due to paralysis of the interossei and lumbrical muscles.
Anatomy and Examination of Ulnar & Sciatic Nerves
The ulnar nerve supplies sensation to the palmar and dorsal surfaces of the little and half of the ring fingers. It can be injured at different levels - high injury near the elbow results in paralysis of all muscles supplied and sensory loss in the hand. Low injury in the forearm causes clawing of the hand. Tardy ulnar palsy occurs later in life due to ischemic changes. Combined low median and ulnar nerve palsy results in intrinsic minus hand. The sciatic nerve supplies the lower limb and injury can cause paralysis and drop foot.
Claw hand
Claw hand, also known as intrinsic minus hand, is caused by an imbalance between strong extrinsic flexors and deficient intrinsics. It is characterized by hyperextension of the MCP joints and flexion of the PIP and DIP joints.
There are several types of claw hand including partial and total. Partial is due to ulnar nerve paralysis and results in clawing of just the ring and little fingers. Total claw hand is caused by combined median and ulnar nerve palsies and leads to clawing of all five fingers.
Various tests can identify which nerves are involved based on the muscles affected. Ulnar nerve tests examine muscles like the first dorsal interossei and hypothenar muscles.

Pharmacology of Drugs for Congestive Heart Failure
Congestive Heart failure is caused by low cardiac output and high sympathetic discharge. Diuretics reduce preload, ACE inhibitors lower afterload, beta blockers reduce sympathetic activity, and digitalis has inotropic effects. Newer medications target vasodilation and myosin activation to improve heart efficiency while lowering energy requirements. Combination therapy, following an assessment of cardiac function and volume status, is the most effective strategy to heart failure care.

Applications of NMR in Protein Structure Prediction.pptx
This presentation explores the pivotal role of Nuclear Magnetic Resonance (NMR) spectroscopy in predicting protein structures. It delves into the methodologies, advancements, and applications of NMR in determining the three-dimensional configurations of proteins, which is crucial for understanding their function and interactions.
Pharmacology of Prostaglandins, Thromboxanes and Leukotrienes
This presentation gives information on the pharmacology of Prostaglandins, Thromboxanes and Leukotrienes i.e. Eicosanoids. Eicosanoids are signaling molecules derived from polyunsaturated fatty acids like arachidonic acid. They are involved in complex control over inflammation, immunity, and the central nervous system. Eicosanoids are synthesized through the enzymatic oxidation of fatty acids by cyclooxygenase and lipoxygenase enzymes. They have short half-lives and act locally through autocrine and paracrine signaling.

STUDIES IN SUPPORT OF SPECIAL POPULATIONS: GERIATRICS E7
Unit 4: MRA 103T Regulatory affairs
This guideline is directed principally toward new Molecular Entities that are
likely to have significant use in the elderly, either because the disease intended
to be treated is characteristically a disease of aging ( e.g., Alzheimer's disease) or
because the population to be treated is known to include substantial numbers of
geriatric patients (e.g., hypertension).
Storyboard on Acne-Innovative Learning-M. pharm. (2nd sem.) Cosmetics
Acne is a common skin condition that occurs when hair follicles become clogged with oil and dead skin cells. It typically manifests as pimples, blackheads, or whiteheads, often on the face, chest, shoulders, or back. Acne can range from mild to severe and may cause emotional distress and scarring in some cases.
**Causes:**
1. **Excess Oil Production:** Hormonal changes during adolescence or certain times in adulthood can increase sebum (oil) production, leading to clogged pores.
2. **Clogged Pores:** When dead skin cells and oil block hair follicles, bacteria (usually Propionibacterium acnes) can thrive, causing inflammation and acne lesions.
3. **Hormonal Factors:** Fluctuations in hormone levels, such as during puberty, menstrual cycles, pregnancy, or certain medical conditions, can contribute to acne.
4. **Genetics:** A family history of acne can increase the likelihood of developing the condition.
**Types of Acne:**
- **Whiteheads:** Closed plugged pores.
- **Blackheads:** Open plugged pores with a dark surface.
- **Papules:** Small red, tender bumps.
- **Pustules:** Pimples with pus at their tips.
- **Nodules:** Large, solid, painful lumps beneath the surface.
- **Cysts:** Painful, pus-filled lumps beneath the surface that can cause scarring.
**Treatment:**
Treatment depends on the severity and type of acne but may include:
- **Topical Treatments:** Such as benzoyl peroxide, salicylic acid, or retinoids to reduce bacteria and unclog pores.
- **Oral Medications:** Antibiotics or oral contraceptives for hormonal acne.
- **Procedures:** Such as chemical peels, extraction of comedones, or light therapy for more severe cases.
**Prevention and Management:**
- **Cleanse:** Regularly wash skin with a gentle cleanser.
- **Moisturize:** Use non-comedogenic moisturizers to keep skin hydrated without clogging pores.
- **Avoid Irritants:** Such as harsh cosmetics or excessive scrubbing.
- **Sun Protection:** Use sunscreen to prevent exacerbation of acne scars and inflammation.
Acne treatment can take time, and consistency in skincare routines and treatments is crucial. Consulting a dermatologist can help tailor a treatment plan that suits individual needs and reduces the risk of scarring or long-term skin damage.
