Administration into the subcutaneous (SC) tissue is a typical route of delivery for therapeutic proteins, especially for frequent treatments, long-term regimens, or self-administration. It is currently believed that the maximum volume for SC injections is approximately 1.5 mL. Larger SC injection volumes are considered to be associated with injection pain and adverse events at the injection site. However, no controlled clinical studies and actual evidence exist to support this assumption. In this review, we discuss current and publically available data related to SC administration volumes. We conclude that injection volumes higher than 3.5 mL are worth exploring if required for the development of efficacious drug treatments. Studying tissue back pressure, injection site leakage, local tolerability, and injection-related adverse events, such as injection pain, should be considered for the development of higher SC injection volumes.

Purpose: Scleral cross-linking (SXL) with ultraviolet A (UVA) and riboflavin has already been used in laboratory studies for scleral stiffness increase as a potential treatment for progressive myopia and scleral ectasia. This study aims to investigate whether the regional application of scleral cross-linking (SXL) with ultraviolet A (UVA) and riboflavin in fresh porcine eye globes affects the ocular rigidity as well as its impact on intraocular pressure after an induced acute increase in the volume of intraocular fluid.
Methods: The study included two groups of fresh porcine eyes: an experimental group (n=20) that underwent scleral cross-linking (SXL) with riboflavin and UVA applied to the posterior sclera and a control group (n=20) that did not receive SXL treatment.
Knee osteoarthritis (KOA) is a healthcare burden affecting over 595 million people worldwide. Recently, intra-articular platelet-rich plasma (PRP) injections from the patient's blood have shown promise in slowing KOA progression due to platelets' regenerative properties. This study aimed to evaluate the optimal dosing and schedule for PRP therapy in managing mild to moderate KOA.

Background: In epidural anaesthesia, the addition of an adjuvant to local anaesthetics enhances the efficacy, thereby providing increased duration and intensity of blockade in lower limb surgeries. The aim was to compare the efficacy, onset, and duration of sensory and motor blockade; haemodynamic changes; and sedative and analgesic effects of nalbuphine, clonidine, and dexmedetomidine as an adjuvant to ropivacaine in epidural anaesthesia.
Methodology: A prospective, randomised, double-blind study among 90 patients after taking consent was divided into three groups (30 patients each; Group D received 15 ml of 0.

Gas bubbles, commonly used in medical ultrasound (US), witness advancements with nanobubbles (NB), providing improved capabilities over microbubbles (MB). NBs offer enhanced penetration into capillaries and the ability to extravasate into tumors following systemic injection, alongside prolonged circulation and persistent acoustic contrast. Low-frequency insonation (<1 MHz) with NBs holds great potential in inducing significant bioeffects, making the monitoring of their acoustic response critical to achieving therapeutic goals.

Introduction: Double-bundle anterior cruciate ligament reconstruction (ACLR) has biomechanical advantages but is associated with increased intraoperative bleeding. The role of tranexamic acid (TXA) in reducing postoperative joint haemarthrosis and improving the short-term outcomes of double-bundle ACLR has not yet been thoroughly investigated. This study aimed to assess the effects of intraoperative TXA on postoperative joint haemarthrosis and short-term functional outcomes in patients who underwent double-bundle ACLR.
