Mesoporous-rich calcium and potassium-activated carbons prepared from degreased spent coffee grounds for efficient removal of MnO in aqueous media.

Commercial ACs typically possess high surface areas and high microporosity. However, ACs with appreciable mesoporosity are growing in consideration and demand because they are beneficial for the adsorption of large species, such as heavy metal ions. Thus, in this study, degreased coffee grounds (DCG) were used as precursors for the production of ACs by means of chemical activation at 600 °C for the efficient removal of manganese in the form of MnO .

A retrospective review of sudden onset severe headache and subarachnoid haemorrhage on the clinical decision unit: looking for a needle in a haystack?

Introduction: Patients commonly present to the Emergency Department with sudden onset acute severe headache, but exclusion of significant secondary causes, particularly subarachnoid haemorrhage (SAH), is vital. The misdiagnosis of SAH is most likely in patients with a normal neurological examination, and the consequences can be disastrous. A noncontrast computed tomography (CT) brain scan is the initial investigation of choice, and most would recommend that, if negative, this be followed by a lumbar puncture (LP) and cerebrospinal fluid (CSF) analysis.

What is a "sense of foreshortened future?" A phenomenological study of trauma, trust, and time.

One of the symptoms of trauma is said to be a "sense of foreshortened future." Without further qualification, it is not clear how to interpret this. In this paper, we offer a phenomenological account of what the experience consists of.

Acyclovir ointment plus topical betamethasone or placebo in first episode disciform keratitis.

Thirty patients with first episode disciform keratitis and with no previous steroid exposure were randomly assigned to double blind treatment with 3% acyclovir ointment and 0.1% betamethasone (Betnesol) drops or acyclovir ointment and matching placebo. In the steroid group 14 of the 15 patients healed in a mean time of 21.

Randomised double-masked trial of lodoxamide and sodium cromoglycate in allergic eye disease. A multicentre study.

135 patients were entered into a 28-day randomized double-masked multicentre study comparing the efficacy and short-term safety of lodoxamide 0.1% ophthalmic solution (Alomide--Alcon Laboratories), a mast cell stabilizer, with sodium cromoglycate 2% ophthalmic solution (Opticrom--Fisons Pharmaceuticals) in the treatment of allergic eye disease. Patients given lodoxamide 0.

Randomised double-blind trial of bromovinyldeoxyuridine (BVDU) and trifluorothymidine (TFT) in dendritic corneal ulceration.

The results of a randomised double-blind clinical trial of 0.1% bromovinyldeoxyuridine (BVDU) and 1% trifluorothymidine (TFT) in 60 patients with corneal dendritic ulceration are presented. There was no significant difference between BVDU and TFT in terms of numbers of ulcers healed (p = 0.

Bromovinyldeoxyuridine (BVDU) and trifluorothymidine (TFT) in dendritic corneal ulceration: a double blind controlled study.

Fifty patients with corneal dendritic ulceration were randomly entered into a double blind clinical trial comparing BVDU eyedrops with TFT eyedrops. Of those receiving TFT 100% healed in a mean time of 6.7 days, while 92% of those receiving BVDU healed in a mean time of 8.

Ocular cicatricial pemphigoid and oesophageal carcinoma.

A 65-year-old man developed ocular cicatricial pemphigoid. He was treated with topical and systemic immunosuppressive agents. Three months later, he was found to have metastatic oesophageal carcinoma.

Randomised double-blind trial of acyclovir and idoxuridine in dendritic corneal ulceration.

The results of a randomised double-blind clinical trial of 3% acyclovir and 0.5% idoxuridine (IDU) ophthalmic ointments in 60 patients with corneal dendritic ulceration are presented. Ulcers in all 30 patients treated with acyclovir healed compared with 22 (76%) of 29 patients treated with IDU (P < 0.
